whereis - Linux Man Page

SYNOPSIS
      whereis [ -bmsu ] [ -BMS directory...  -f ] filename ...

DESCRIPTION
      whereis locates source/binary and manuals sections for specified files.
      The  supplied  names  are first stripped of leading pathname components
      and any (single) trailing extension of the form .ext, for example,  .c.
      Prefixes  of  s.   resulting  from  use of source code control are also
      dealt with.  whereis then attempts to locate the desired program  in  a
      list of standard Linux places.

OPTIONS
      -b     Search only for binaries.

      -m     Search only for manual sections.

      -s     Search only for sources.

      -u     Search  for unusual entries.  A file is said to be unusual if it
             does  not  have  one  entry  of  each  requested   type.    Thus
             `whereis  -m  -u  *'  asks for those files in the current direc-
             tory which have no documentation.

      -B     Change or otherwise limit the places where whereis searches  for
             binaries.

      -M     Change  or otherwise limit the places where whereis searches for
             manual sections.

      -S     Change or otherwise limit the places where whereis searches  for
             sources.

      -f     Terminate  the last directory list and signals the start of file
             names, and must be used when any of the -B, -M,  or  -S  options
             are used.

EXAMPLE
      Find  all  files  in /usr/bin which are not documented in /usr/man/man1
      with source in /usr/src:

             example% cd /usr/bin
             example% whereis -u -M /usr/man/man1 -S /usr/src -f *

FILES
      /{bin,sbin,etc}

      /usr/{lib,bin,old,new,local,games,include,etc,src,man,sbin,
                          X386,TeX,g++-include}

      /usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}
