二十几个有用的linux工具

Just a list of 20 (now 28) tools for the command line. Some are little-known, some are just too useful to miss, some are pure obscure -- I hope you find something useful that you weren't aware of yet! Use your operating system's package manager to install most of them. (Thanks for the tips, everybody!)

Discussion of this post on Hacker News - that's the place to get into nice old-school FidoNet-style flame wars about the important things in life, like whether or not tmux is better than screen, is parallel better than xargs, whether or not ifconfig is a power tool, or should this list include somebody's once-used tool for converting old Pascal code to C or something.
