Find default Debian commands based on shell built-in commands and coreutils packages

Remember to see man pages. It's your first help ! Don't recreate or import man or info pages here.

Good informations are:

  • Simple description
  • Some useful examples that are not in man pages

You don't find this shell command on your system, see next URL and replace MY_COMMAND by your command

http://packages.debian.org/search?suite=default&section=all&arch=any&searchon=contents&keywords=MY_COMMAND

ShellToolTricks, PrincipalCommands and coreutils should be merging here
