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.

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 `/'.

       whereis has a hard-coded path, so may not always find what you're looking for.

AVAILABILITY
       The  whereis  command  is  part	of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-
       linux/.
