Locating another command or program (whereis command)

The whereis command locates the source, binary, and manuals sections for specified files. The command attempts to find the desired program from a list of standard locations.

See the following examples:
  • To find files in the current directory that have no documentation, type the following:
    whereis -m -u *
  • To find all of the files that contain the name Mail, type the following:
    whereis Mail
    The system displays information similar to the following:
    Mail: /usr/bin/Mail /usr/lib/Mail.rc
