WHEREIS(1)

NAME
       whereis - locate the binary, source, and manual page files
       for a command

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:
              /bin
              /usr/bin
              /etc
              /usr/etc
              /sbin
              /usr/sbin
              /usr/games
              /usr/games/bin
              /usr/emacs/etc
              /usr/lib/emacs/19.22/etc
              /usr/lib/emacs/19.23/etc
              /usr/lib/emacs/19.24/etc
              /usr/lib/emacs/19.25/etc
              /usr/lib/emacs/19.26/etc
              /usr/lib/emacs/19.27/etc
              /usr/lib/emacs/19.28/etc
              /usr/lib/emacs/19.29/etc
              /usr/lib/emacs/19.30/etc
              /usr/TeX/bin
              /usr/tex/bin
              /usr/interviews/bin/LINUX
              /usr/bin/X11
              /usr/X11/bin
              /usr/X11R5/bin
              /usr/X11R6/bin
              /usr/X386/bin
              /usr/local/bin
              /usr/local/etc
              /usr/local/sbin
              /usr/local/games
              /usr/local/games/bin
              /usr/local/emacs/etc
              /usr/local/TeX/bin
              /usr/local/tex/bin
              /usr/local/bin/X11
              /usr/contrib",
              /usr/hosts",
              /usr/include",
              /usr/g++-include",

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 directory 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}

       SEE ALSO
              chdir(2V)

BUGS
       Since  whereis  uses  chdir(2V)  to  run faster, pathnames
       given with the -M, -S, or -B must be full; that  is,  they
       must begin with a `/'.
