By Mel Beckman, InfoWorld |  Software, command line, Mac OS X

For most people, the Mac's OS X is all about the graphical user interface. But system administrators and power users know that the Mac's command-line interface can be a powerful time saver and, in many cases, the only method to accomplish certain tasks. The command shell itself, delivered by Apple's included lTerminal program, is a wonder of open source. Bash -- for "Bourne again shell" -- was developed by free-software guru Brian Fox. It's widely used on operating systems of all kinds, including iOS, Linux, Unix, and mainframes.

All commands, unless otherwise noted, run on all versions of OS X since 10.4 Tiger. For most of these commands, you can get more documentation using the "manpage" system: Type man followed by the command name. For example, man lsof displays the manual page for the List Open Files command.
