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

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

       whereis	locates  source/binary	and  manuals  sections for specified files.  The supplied
       names are first stripped of leading pathname components and any (single)  trailing  exten-
       sion 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.

       -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.

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

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





       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.

       The whereis command is part of the util-linux package and is available from ftp://ftp.ker-
