This page contains quick cheats for variants of Unix. Some are specific to only one flavor of Unix (i.e. Solaris), but many can be applied to any Unix flavor (i.e. vi tricks). I make no attempt to document the obvious or simple use cases; please refer to the man pages or product documentation to understand the commands before using them.
