"drive" -Google Drive client for the commandline



Build Status
drive is a tiny program to pull or push Google Drive files.
drive was originally developed by Burcu Dogan while working on the Google Drive team. Since she is very busy and no longer able to maintain it, I took over drive on Thursday, 1st January 2015. This repository contains the latest version of the code.

Table of Contents

Requirements

go 1.5.X or higher is required. See here for installation instructions and platform installers.
  • Make sure to set your GOPATH in your env, .bashrc or .bash_profile file. If you have not yet set it, you can do so like this:
$ cat << ! >> ~/.bashrc
> export GOPATH=\$HOME/gopath
> export PATH=\$GOPATH:\$GOPATH/bin:\$PATH
> !
$ source ~/.bashrc # To reload the settings and get the newly set ones # Or open a fresh terminal
The above setup will ensure that the drive binary after compilation can be invoked from your current path.

Installation

To install from the latest source, run:
$ go get -u github.com/odeke-em/drive/cmd/drive
Otherwise:
  • In order to address issue #138, where debug information should be bundled with the binary, you'll need to run:
$ go get github.com/odeke-em/drive/drive-gen && drive-gen
In case you need a specific binary e.g for Debian folks issue #271 and issue 277
$ go get -u github.com/odeke-em/drive/drive-google
That should produce a binary drive-google
OR
To bundle debug information with the binary, you can run:
$ go get -u github.com/odeke-em/drive/drive-gen && drive-gen drive-google

Godep

  • Using godep
$ cd $GOPATH/src/github.com/odeke-em/drive/drive-gen && godep save
  • Unravelling/Restoring dependencies
$ cd $GOPATH/src/github.com/odeke-em/drive/drive-gen && godep restore
Please see file drive-gen/README.md for more information.

Platform Packages

For curated packages on your favorite platform, please see file Platform Packages.md.
Is your platform missing a package? Feel free to prepare / contribute an installation package and then submit a PR to add it in.

Cross Compilation

See file Makefile which currently supports cross compilation. Just run make and then inspect the binaries in directorybin.
  • Supported platforms to cross compile to:
  • ARMv5.
  • ARMv6.
  • ARMv7.
  • ARMv8.
  • Darwin (OS X).
  • Linux.
Also inspect file bin/md5Sums.txt after the cross compilation.

Configuration

Optionally set the GOOGLE_API_CLIENT_ID and GOOGLE_API_CLIENT_SECRET environment variables to use your own API keys.

Usage

Initializing

Before you can use drive, you'll need to mount your Google Drive directory on your local file system:
$ drive init ~/gdrive
$ cd ~/gdrive

De Initializing

The opposite of drive init, it will remove your credentials locally as well as configuration associated files.
$ drive deinit [--no-prompt]
For a complete deinit-ialization, don't forget to revoke account access, please see revoking account access

Traversal Depth

Before talking about the features of drive, it is useful to know about "Traversal Depth".
Throughout this README the usage of the term "Traversal Depth" refers to the number of
nodes/hops/items that it takes to get from one parent to children. In the options that allow it, you'll have a flag option --depth <n> where n is an integer
  • Traversal terminates on encountering a zero 0 traversal depth.
  • A negative depth indicates infinity, so traverse as deep as you can.
  • A positive depth helps control the reach.
Given:
|- A/
    |- B/
    |- C/
        |- C1
        |- C2
            |- C10/
            |- CTX/
                | - Music
                | - Summary.txt
  • Items on the first level relative to A/ ie depth 1, we'll have:
    B, C
  • On the third level relative to C/ ie depth 3
    • We'll have:
      Items: Music, Summary.txt
    • The items encountered in depth 3 traversal relative to C/ are:
            |- C1
      |- C2
          |- C10/
          |- CTX/
              | - Music
              | - Summary.txt
  • No items are within the reach of depth -1 relative to B/ since B/ has no children.
  • Items within the reach of depth - relative to CTX/ are:
            | - Music
        | - Summary.txt

Pulling

The pull command downloads data that does not exist locally but does remotely on Google drive, and may delete local data that is not present on Google Drive. Run it without any arguments to pull all of the files from the current path:
$ drive pull
To pull and decrypt your data that is stored encrypted at rest on Google Drive, use flag --decryption-password:
$ drive pull --decryption-password "$JiME5Umf" influx.txt
Pulling by matches is also supported
$ cd ~/myDrive/content/2015
$ drive pull --matches vines docx
To force download from paths that otherwise would be marked with no-changes
$ drive pull -force
To pull specific files or directories, pass in one or more paths:
$ drive pull photos/img001.png docs
Pulling by id is also supported
$ drive pull --id 0fM9rt0Yc9RTPaDdsNzg1dXVjM0E 0fM9rt0Yc9RTPaTVGc1pzODN1NjQ 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU
pull optionally allows you to pull content up to a desired depth.
Say you would like to get just folder items until the second level
$ drive pull --depth 2 heavy-files summaries
Traverse deep to infinity and beyond
$ drive pull --depth -1 all-my-files
Pulling starred files is allowed as well
$ drive pull --starred
$ drive pull --starred --matches content
$ drive pull --starred --all # Pull all the starred files that aren't in the trash
$ drive pull --starred --all --trashed # Pull all the starred files in the trash
Like most commands .driveignore can be used to filter which files to pull.
To selectively pull by type e.g file vs directory/folder, you can use flags
  • files
  • directories
$ drive pull --files a1/b2
$ drive pull --directories tf1

Note: Checksum verification:

  • By default checksum-ing is turned off because it was deemed to be quite vigorous and unnecessary for most cases.
  • Due to popular demand to cover the common case in which size + modTime differences are sufficient to detect file changes. The discussion stemmed from issue #117.
    To turn checksum verification back on:
$ drive pull -ignore-checksum=false
drive also supports piping pulled content to stdout which can be accomplished by:
$ drive pull -piped path1 path2
  • In relation to issue #529, you can change the max retry counts for exponential backoff. Using a count < 0 falls back to the default count of 20:
$ drive pull --retry-count 14 documents/2016/March videos/2013/September

Exporting Docs

By default, the pull command will export Google Docs documents as PDF files. To specify other formats, use the -export option:
$ drive pull -export pdf,rtf,docx,txt
To explicitly export instead of using --force
$ drive pull --export pdf,rtf,docx,txt --explicitly-export
By default, the exported files will be placed in a new directory suffixed by \_exports in the same path. To export the files to a different directory, use the -export-dir option:
$ drive pull -export pdf,rtf,docx,txt -export-dir ~/Desktop/exports
Supported formats:
  • doc, docx
  • jpeg, jpg
  • gif
  • html
  • odt
  • rtf
  • pdf
  • png
  • ppt, pptx
  • svg
  • txt, text
  • xls, xlsx

Pushing

The push command uploads data to Google Drive to mirror data stored locally.
Like pull, you can run it without any arguments to push all of the files from the current path, or you can pass in one or more paths to push specific files or directories.
push also allows you to push content up to a desired traversal depth e.g
$ drive push --depth 1 head-folders
You can also push multiple paths that are children of the root of the mounted drive to a destination,
in relation to issue #612, using key --destination:
For example to push the content of music/Travi$+Future, integrals/complex/compilations directly to a1/b2/c3:
$ drive push --destination a1/b2/c3 music/Travi$+Future integrals/complex/compilations
Note: To ignore checksum verification during a push:
$ drive push -ignore-checksum
To keep your data encrypted at rest remotely on Google Drive:
$ drive push --encryption-password "$JiME5Umf" influx.txt
For E2E discussions, see issue #543:
drive also supports pushing content piped from stdin which can be accomplished by:
$ drive push -piped path
To selectively push by type e.g file vs directory/folder, you can use flags
  • files
  • directories
$ drive push --files a1/b2
$ drive push --directories tf1
Like most commands .driveignore can be used to filter which files to push.
Here is an example using drive to backup the current working directory. It pushes a tar.gz archive created on the fly. No archive file is made on the machine running the command, so it doesn't waste disk space.
$ tar czf - . | drive push -piped backup-$(date +"%m-%d-%Y-"%T"").tar.gz
  • Note:
    • In response to #107 and numerous other issues related to confusion about clashing paths, drive can now auto-rename clashing files. Use flag --fix-clashes during a pull or push, and drive will try to rename clashing files by adding a unique suffix at the end of the name, but right before the extension of a file (if the extension exists). If you haven't passed in the above --fix-clashes flag, drive will abort on trying to deal with clashing names. If you'd like to turn off this safety, pass in flag --ignore-name-clashes
    • In relation to #57 and @rakyll's #49. A couple of scenarios in which data was getting totally clobbered and unrecoverable, drive now tries to play it safe and warn you if your data could potentially be lost e.g during a to-disk clobber for which you have no backup. At least with a push you have the luxury of untrashing content. To disable this safety, run drive with flag -ignore-conflict e.g:
    $ drive pull -ignore-conflict collaboration_documents
    Playing the safety card even more, if you want to get changes that are non clobberable ie only additions run drive with flag -no-clobber e.g:
    $ drive pull -no-clobber Makefile
    • Ordinarily your system will not traverse nested symlinks e.g:
      $ mkdir -p a/b
  $ mkdir -p ~/Desktop/z1/z2 && ls ~ > ~/Desktop/z1/z2/listing.txt
  $ ln -s ~/Desktop/z1/z2 a/b
  $ ls -R a # Should print only z2 and nothing inside it.
    However in relation to #80, for purposes of consistency with your Drive, traversing symlinks has been added.
For safety with non clobberable changes i.e only additions:
$ drive push -no-clobber
  • Due to the reasons above, drive should be able to warn you in case of total clobbers on data. To turn off this behaviour/safety, pass in the -ignore-conflict flag i.e:
$ drive push -force sure_of_content
To push without user input (i.e. without prompt)
$ drive push -quiet
or
$ drive push -no-prompt
To get Google Drive to convert a file to its native Google Docs format
$ drive push -convert
Extra features: to make Google Drive attempt Optical Character Recognition (OCR) for png, gif, pdf and jpg files.
$ drive push -ocr
Note: To use OCR, your account should have this feature. You can find out if your account has OCR allowed.
$ drive features

Note:

  • MimeType inference is from the file's extension.
    If you would like to coerce a certain mimeType that you'd prefer to assert with Google Drive pushes, use flag -coerce-mime <short-key> See List of MIME type short keys for the full list of short keys.
$ drive push -coerce-mime docx my_test_doc
  • Excluding certain operations can be done both for pull and push by passing in flag --exclude-ops
e.g
$ drive pull --exclude-ops "delete,update" vines
$ drive push --exclude-ops "create" sensitive_files
  • To show more information during pushes or pulls e.g show the current operation, pass in option --verbose e.g:
$ drive pull --verbose 2015/Photos content
$ drive push --verbose Music Fall2014
  • In relation to issue #529, you can change the max retry counts for exponential backoff. Using a count < 0 falls back to the default count of 20:
$ drive push --retry-count 4 a/bc/def terms

End to End Encryption

This can be toggled when you supply a non-empty password ie
  • --encryption-password for a push.
  • --decryption-password for a pull.
When you supply argument --encryption-password during a push, drive will encrypt your data and store it remotely encrypted(stored encrypted at rest), it can only be decrypted by you when you perform a pull with the respective arg --decryption-password.
$ drive push --encryption-password "$400lsGO1Di3" few-ones.mp4 newest.mkv
$ drive pull --decryption-password "$400lsGO1Di3" few-ones.mp4 newest.mkv
If you supply the wrong password, you'll be warned if it cannot be decrypted
$ drive pull --decryption-password "4nG5troM" few-ones.mp4 newest.mkv
message corrupt or incorrect password
To pull normally push or pull your content, without attempting any *cryption attempts, skip passing in a password and no attempts will be made.

Publishing

The pub command publishes a file or directory globally so that anyone can view it on the web using the link returned.
$ drive pub photos
  • Publishing by fileId is also supported
$ drive pub --id 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU 0fM9rt0Yc9RTPSTZEanBsamZjUXM

Unpublishing

The unpub command is the opposite of pub. It unpublishes a previously published file or directory.
$ drive unpub photos
  • Publishing by fileId is also supported
$ drive unpub --id 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU 0fM9rt0Yc9RTPSTZEanBsamZjUXM

Sharing and Emailing

The share command enables you to share a set of files with specific users and assign them specific roles as well as specific generic access to the files. It also allows for email notifications on share.
$ drive share --emails odeke@ualberta.ca,odeke.ex@gmail.com --message "This is the substring file I told you about" --role reader,writer -type group mnt/substringfinder.c projects/kmp.c
$ drive share --emails emm.odeke@gmail.com,odeke@ualberta.ca --role reader,commenter --type user influx traversal/notes/conquest
For example to share a file with users of a mailing list and a custom message
$ drive share -emails drive-mailing-list@gmail.com -message "Here is the drive code" -role group mnt/drive
  • Also supports sharing by fileId
$ drive share --emails developers@developers.devs --message "Developers, developers developers" --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Unsharing

The unshare command revokes access of a specific accountType to a set of files.
When no --role is given it by default assumes you want to revoke all access ie "reader", "writer", "commenter"
$ drive unshare -type group mnt/drive
$ drive unshare --emails  emm.odeke@gmail.com,odeke@ualberta.ca --type user,group --role reader,commenter infinity newfiles/confidential
  • Also supports unsharing by fileId
$ drive unshare --type group --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Diffing

The diff command compares local files with their remote equivalents. It allows for multiple paths to be passed in e.g
$ drive diff changeLogs.log notes sub-folders/
You can diff to a desired depth
$ drive diff --depth 2 sub-folders/ contacts/ listings.txt
You can also switch the base, either local or remote by using flag --base-local
$ drive diff --base-local=true assignments photos # To use local as the base
$ drive diff --base-local=false infocom photos # To use remote as the base
You can only diff for short changes that is only name differences, file modTimes and types, you can use flag --skip-content-check.
$ drive diff --skip-content-check

Touching

Files that exist remotely can be touched i.e their modification time updated to that on the remote server using the touchcommand:
$ drive touch Photos/img001.png logs/log9907.txt
For example to touch all files that begin with digits 0 to 9:
$ drive touch -matches $(seq 0 9)
  • Also supports touching of files by fileId
$ drive touch --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
  • You can also touch files to a desired depth of nesting within their parent folders.
$ drive touch --depth 3 mnt newest flux
$ drive touch --depth -1 --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
$ drive touch --depth 1 --matches $(seq 0 9)

Trashing and Untrashing

Files can be trashed using the trash command:
$ drive trash Demo
To trash files that contain a prefix match e.g all files that begin with Untitled, or Make
Note: This option uses the current working directory as the parent that the paths belong to.
$ drive trash -matches Untitled Make
Files that have been trashed can be restored using the untrash command:
$ drive untrash Demo
To untrash files that match a certain prefix pattern
$ drive untrash -matches pQueue photos Untitled
  • Also supports trashing/untrashing by fileId
$ drive trash --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
$ drive untrash --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Emptying the Trash

Emptying the trash will permanently delete all trashed files. Caution: They cannot be recovered after running this command.
$ drive emptytrash

Deleting

Deleting items will PERMANENTLY remove the items from your drive. This operation is irreversible.
$ drive delete flux.mp4
$ drive delete --matches onyx swp
  • Also supports deletion by fileIds
$ drive delete --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Listing Files

The list command shows a paginated list of files present remotely.
Run it without arguments to list all files in the current directory's remote equivalent:
$ drive list
Pass in a directory path to list files in that directory:
$ drive list photos
To list matches
$ drive list --matches mp4 go
The -trashed option can be specified to show trashed files in the listing:
$ drive list -trashed photos
To get detailed information about the listings e.g owner information and the version number of all listed files:
$ drive list -owners -l -version
  • Also supports listing by fileIds
$ drive list -depth 3 --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
  • Listing allows for sorting by fields e.g name, version, size,modtime, lastModifiedByMeTimelvt,md5. To do this in reverse order, suffix_ror-` to the selected key
e.g to first sort by modTime, then largest-to-smallest and finally most number of saves:
$ drive list --sort modtime,size_r,version_r Photos
  • For advanced listing
$ drive list --skip-mime mp4,doc,txt
$ drive list --match-mime xls,docx
$ drive list --exact-title url_test,Photos

Stating Files

The stat commands show detailed file information for example people with whom it is shared, their roles and accountTypes, and fileId etc. It is useful to help determine whom and what you want to be set when performing share/unshare
$ drive stat mnt
By default stat won't recursively stat a directory, to enable recursive stating:
$ drive stat -r mnt
  • Also supports stat-ing by fileIds
$ drive stat -r --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U
OR
$ drive stat -depth 4 --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U

Retrieving md5 Checksums

The md5sum command quickly retrieves the md5 checksums of the files on your drive. The result can be fed into the "md5sum -c" shell command to validate the integrity of the files on Drive versus the local copies.
Check that files on Drive are present and match local files:
~/MyDrive/folder$ drive md5sum | md5sum -c
Do a two-way diff (will also locate files missing on either side)
~/MyDrive/folder$ diff <(drive md5sum) <(md5sum *)
Same as above, but include subfolders
~/MyDrive/folder$ diff <(drive md5sum -r) <(find * -type f | sort | xargs md5sum)
Compare across two different Drive accounts, including subfolders
~$ diff <(drive md5sum -r MyDrive/folder) <(drive md5sum -r OtherDrive/otherfolder)
  • Note: Running the 'drive md5sum' command retrieves pre-computed md5 sums from Drive; its speed is proportional to the number of files on Drive. Running the shell 'md5sum' command on local files requires reading through the files; its speed is proportional to the size of the files._

New File

drive allows you to create an empty file or folder remotely Sample usage:
$ drive new --folder flux
$ drive new --mime-key doc bofx
$ drive new --mime-key folder content
$ drive new --mime-key presentation ProjectsPresentation
$ drive new --mime-key sheet Hours2015Sept
$ drive new --mime-key form taxForm2016 taxFormCounty
$ drive new flux.txt oxen.pdf # Allow auto type resolution from the extension

Editing Description

You can edit the description of a file like this
$ drive edit-desc --description "This is a new file description" freshFolders/1.txt commonCore/
$ drive edit-description --description "This is a new file description" freshFolders/1.txt commonCore/
Even more conveniently by piping content
$ cat fileDescriptions | drive edit-desc --piped  targetFile influx/1.txt

FileId Retrieval

You can retrieve just the fileId for specified paths
$ drive id [--depth n] [paths...]
$ drive file-id [--depth n] [paths...]
For example:
$ drive file-id --depth 2 dup-tests bug-reproductions
$ # drive file-id --depth 2 dup-tests bug-reproductions
FileId                                           Relative Path
"0By5qKlgRJeV2NB1OTlpmSkg8TFU"                   "/dup-tests"
"0Bz5wQlgRJeP2QkRSenBTaUowU3c"                   "/dup-tests/influx_0"
"0Cu5wQlgRJeV2d2VmY29HV217TFE"                   "/dup-tests/a"
"0Cy5wQlgRJeX2WXVFMnQyQ2NDRTQ"                   "/dup-tests/influx"
"0Cy5wQlgRJeP2YGMiOC15OEpUZnM"                   "/bug-reproductions"
"0Cy5wQlgRJeV2MzFtTm50NVV5NW8"                   "/bug-reproductions/drive-406"
"1xmXPziMPEgq2dK-JqaUytKz_By8S_7_RVY79ceRoZwv"   "info-bulletins"

Quota

The quota command prints information about your drive, such as the account type, bytes used/free, and the total amount of storage available.
$ drive quota

Features

The features command provides information about the features present on the drive being queried and the request limit in queries per second
$ drive features

About

The about command provides information about the program as well as that about your Google Drive. Think of it as a hybrid between the features and quota commands.
$ drive about
OR for detailed information
$ drive about -features -quota

Help

Run the help command without any arguments to see information about the commands that are available:
$ drive help
Pass in the name of a command to get information about that specific command and the options that can be passed to it.
$ drive help push
To get help for all the commands
$ drive help all

Copying

drive allows you to copy content remotely without having to explicitly download and then reupload.
$ drive copy -r blobStore.py mnt flagging
$ drive copy blobStore.py blobStoreDuplicated.py
  • Also supports copying by fileIds
$ drive copy -r --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U ../content

Rename

drive allows you to rename a file/folder remotely. Two arguments are required to rename ie <relativePath/To/source or Id> <newName>.
To perform a rename:
$ drive rename url_test url_test_results
$ drive rename openSrc/2015 2015-Contributions
  • Also supports renaming by fileId
$ drive rename 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 fluxing
To turn off renaming locally or remotely, use flags --local=false or --remote=false. By default both are turned on.
For example
$ drive rename --local=false --remote=true a/b/c/d/e/f flux

Clashes

You can deal with clashes by using command drive clashes.
  • To list clashes, you can do
$ drive clashes [--depth n] [paths...]
$ drive clashes --list [--depth n] [paths...] # To be more explicit
  • To fix clashes, you can do:
$ drive clashes --fix [--depth n] [paths...]

Move

drive allows you to move content remotely between folders. To do so:
$ drive move photos/2015 angles library archives/storage
  • Also supports moving by fileId
$ drive move --id 0fM9rt0Yc9RTPeHRfRHRRU0dIY97 0fM9rt0Yc9kJRPSTFNk9kSTVvb0U ../../new_location

DriveIgnore

drive allows you to specify a '.driveignore' file similar to your .gitignore, in the root directory of the mounted drive. Blank lines and those prefixed by '#' are considered as comments and skipped.
For example:
$ cat << $ >> .driveignore
> # My drive ignore file
> \.gd$
> \.so$
> \.swp$
> $
Note:
  • Pattern matching and suffixes are done by regular expression matching so make sure to use a valid regular expression suffix.
  • Go doesn't have a negative lookahead mechanism ie exclude all but which would normally be achieved in other languages or regex engines by "?!". See https://groups.google.com/forum/#!topic/golang-nuts/7qgSDWPIh_E. This was reported and requested in issue #535. A use case might be ignoring all but say .bashrc files or .dotfiles. To enable this, prefix "!" at the beginning of the path to achieve this behavior.
Sample .driveignore with the include and exclude clauses combined.
$ cat << $ >> .driveignore
> ^\.
> !^\.bashrc # .bashrc files won't be ignored
> _export$ # _export files are to be ignored
> !must_export$ # the exception to the clause anything with "must_export"$ won't be ignored

DriveRC

drive supports resource configuration files (.driverc) that you can place both globally(in your home directory) and locally(in the mounted drive dir) or in the directory that you are running an operation from, relative to the root. The entries for a .driverc file is in the form a key-value pair where the key is any of the arguments that you'd get from running
$ drive <command> -h
$ # e.g
$ drive push -h
and the value is the argument that you'd ordinarily supply on the commandline
For example:
$ cat << ! >> ~/.driverc
> # My global .driverc file
> exports=doc,pdf
> depth=100
> no-prompt=true
> !
$
$ cat << ! >> ~/emm.odeke-drive/.driverc
> # The root main .driverc

DesktopEntry

As previously mentioned, Google Docs, Drawings, Presentations, Sheets etc and all files affiliated with docs.google.com cannot be downloaded raw but only exported. Due to popular demand, Linux users desire the ability to have *.desktop files that enable the file to be opened appropriately by an external opener. Thus by default on Linux, drive will create *.desktop files for files that fall into this category.

Command Aliases

drive supports a few aliases to make usage familiar to the utilities in your shell e.g:
  • cp : copy
  • ls : list
  • mv : move
  • rm : delete

Index Prune

  • index
If you would like to fetch missing index files for files that would otherwise not need any modifications, run:
$ drive index path1 path2 path3/path3.1 # To fetch any missing indices in those paths
$ drive index --id 0CLu4lbUI9RTRM80k8EMoe5JQY2z
You can also fetch specific files by prefix matches
$ drive index --matches mp3 jpg
  • prune
In case you might have deleted files remotely but never using drive, and feel like you have stale indices, running drive index --prune will search your entire indices dir for index files that do not exist remotely and remove those ones
$ drive index --prune
  • prune-and-index To combine both operations (prune and then fetch) for indices:
$ drive index --all-ops

Url

The url command prints out the url of a file. It allows you to specify multiple paths relative to root or even by id
$ drive url Photos/2015/07/Releases intros/flux
$ drive url --id  0Bz5qQkvRAeVEV0JtZl4zVUZFWWx  1Pwu8lzYc9RTPTEpwYjhRMnlSbDQ 0Cz5qUrvDBeX4RUFFbFZ5UXhKZm8

Open

The open command allows for files to be opened by the default file browser, default web browser, either by path or by id for paths that exist atleast remotely
$ drive open --file-browser=false --web-browser f1/f2/f3 jamaican.mp4
$ drive open --file-browser --id 0Bz8qQkpZAeV9T1PObvs2Y3BMQEj 0Y9jtQkpXAeV9M1PObvs4Y3BNRFk

Drive server

To enable services like qr-code sharing, you'll need to have the server running that will serve content once invoked in a web browser to allow for resources to be accessed on another device e.g your mobile phone
$ go get github.com/odeke-em/drive/drive-server && drive-server
$ drive-server
Pre-requisites:
  • DRIVE_SERVER_PUB_KEY
  • DRIVE_SERVER_PRIV_KEY
Optionally
  • DRIVE_SERVER_PORT : default is 8010
  • DRIVE_SERVER_HOST : default is localhost
If the above keys are not set in your env, you can do this
$ DRIVE_SERVER_PUB_KEY=<pub_key> DRIVE_SERVER_PRIV_KEY=<priv_key> [DRIVE...] drive-server

QR Code Share

Instead of traditionally copying long links, drive can now allow you to share a link to a file by means of a QR code that is generated after a redirect through your web browser.
From then on, you can use your mobile device or any other QR code reader to get to that file. In order for this to run, you have to have the drive-server running
As long as the server is running on a known domain, then you can start the qr-link getting ie
$ drive qr vines/kevin-hart.mp4 notes/caches.pdf
$ drive qr --address http://192.168.1.113:8010 books/newest.pdf maps/infoGraphic.png
$ drive qr --address https://my.server books/newest.pdf maps/infoGraphic.png
That should open up a browser with the QR code that when scanned will open up the desired file.

Star Or Unstar

To star or unstar documents,
$ drive star information quest/A/B/C
$ drive star --id 0fM9rt0Yc9RTPaDdsNzg1dXVjM0E 0fM9rt0Yc9RTPaTVGc1pzODN1NjQ 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU
$ drive unstar information quest/A/B/C
$ drive unstar --id 0fM9rt0Yc9RTPaDdsNzg1dXVjM0E 0fM9rt0Yc9RTPaTVGc1pzODN1NjQ 0fM9rt0Yc9RTPV1NaNFp5WlV3dlU

Filing Issues

In case of any issue, you can file one by using command issue aka report-issue aka report. It takes flags --title--body --piped.
  • If --piped is set, it expects to read the body from standard input.
A successful issue-filing request will open up the project's issue tracker in your web browser.
$ drive issue --title "Can't open my file" --body "Drive trips out everytime"
$ drive report-issue --title "Can't open my file" --body "Drive trips out everytime"
$ cat bugReport.txt | drive issue --piped --title "push: dump on pushing from this directory"

Revoking Account Access

To revoke OAuth Access of drive to your account, when logged in with your Google account, go tohttps://security.google.com/settings/security/permissions and revoke the desired permissions

Uninstalling

To remove drive from your computer, you'll need to take out:
  • $GOPATH/bin/drive
  • $GOPATH/src/github.com/odeke-em/drive
  • $GOPATH/pkg/github.com/odeke-em/drive
  • $GOPATH/pkg/github.com/odeke-em/drive.a
  • Also do not forget to revoke drive's access in case you need to uninstall it.

Applying patches

To apply patches of code e.g in the midst of bug fixes, you'll just need a little bit of git fiddling.
For example to patch your code with that on remote branch patch-1, you'll need to go into the source code directory, fetch all content from the git remote, checkout the patch branch then run the go installation: something like this.
$ cd $GOPATH/src/github.com/odeke-em/drive
$ git fetch --all
$ git checkout patch-1
$ git pull origin patch-1
$ go get github.com/odeke-em/drive/cmd/drive

Why another Google Drive client?

Background sync is not just hard, it is stupid. Here are my technical and philosophical rants about why it is not worth to implement:
  • Too racy. Data is shared between your remote resource, local disk and sometimes in your sync daemon's in-memory structs. Any party could touch a file at any time. It is hard to lock these actions. You end up working with multiple isolated copies of the same file and trying to determine which is the latest version that should be synced across different contexts.
  • It requires great scheduling to perform best with your existing environmental constraints. On the other hand, file attribute have an impact on the sync strategy. Large files block -- you wouldn't like to sit on and wait for a VM image to get synced before you can start working on a tiny text file.
  • It needs to read your mind to understand your priorities. Which file do you need most? It needs to read your mind to foresee your future actions. I'm editing a file, and saving the changes time to time. Why not to wait until I feel confident enough to commit the changes remotely?
drive is not a sync daemon, it provides:
  • Upstreaming and downstreaming. Unlike a sync command, we provide pull and push actions. The user has the opportunity to decide what to do with their local copy and when they decide to. Make some changes, either push the file remotely or revert it to the remote version. You can perform these actions with user prompt:
    $ echo "hello" > hello.txt
$ drive push # pushes hello.txt to Google Drive
$ echo "more text" >> hello.txt
$ drive pull # overwrites the local changes with the remote version
  • Allowing to work with a specific file or directory, optionally not recursively. If you recently uploaded a large VM image to Google Drive, yet only a few text files are required for you to work, simply only push/pull the exact files you'd like to worth with:
    $ echo "hello" > hello.txt
$ drive push hello.txt # pushes only the specified file
$ drive pull path/to/a/b path2/to/c/d/e # pulls the remote directory recursively
  • Better I/O scheduling. One of the major goals is to provide better scheduling to improve upload/download times.
  • Possibility to support multiple accounts. Pull from or push to multiple Google Drive remotes. Possibility to support multiple backends. Why not to push to Dropbox or Box as well?

Known issues

  • It probably doesn't work on Windows.
  • Google Drive allows a directory to contain files/directories with the same name. Client doesn't handle these cases yet. We don't recommend you to use drive if you have such files/directories to avoid data loss.
  • Racing conditions occur if remote is being modified while we're trying to update the file. Google Drive provides resource versioning with ETags, use Etags to avoid racy cases.
  • drive rejects reading from namedPipes because they could infinitely hang. See issue #208.
