							WHEREIS(1)							    WHEREIS(1)

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

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}

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 look-
       ing for.

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