whereis

WHEREIS(1)							   User Commands							WHEREIS(1)

NAME

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

SYNOPSIS

       whereis [options] [-BMS directory... -f] name...

DESCRIPTION

       whereis	locates  the  binary,  source  and manual files for the specified command names.  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 the standard Linux places, and in the places
       specified by $PATH and $MANPATH.

OPTIONS

       -b     Search only for binaries.

       -m     Search only for manuals.

       -s     Search only for sources.

       -u     Only show the command names that have unusual entries.  A command is said to be unusual if it does not have just one entry  of  each
	      explicitly  requested  type.  Thus 'whereis -m -u *' asks for those files in the current directory which have no documentation file,
	      or more than one.

       -B list
	      Limit the places where whereis searches for binaries, by a whitespace-separated list of directories.

       -M list
	      Limit the places where whereis searches for manuals, by a whitespace-separated list of directories.

       -S list
	      Limit the places where whereis searches for sources, by a whitespace-separated list of directories.

       -f     Terminates the directory list and signals the start of filenames.  It must be used when any of the -B, -M, or -S options is used.

       -l     Output list of effective lookup paths the whereis is using.  When non of -B, -M, or -S is specified the option will out  hard  coded
	      paths that the command was able to find on system.

EXAMPLE

       To find all files in /usr/bin which are not documented in /usr/man/man1 or have no source in /usr/src:

	      $ cd /usr/bin
	      $ whereis -u -ms -M /usr/man/man1 -S /usr/src -f *

FILE SEARCH PATHS

       By default whereis tries to find files from hard-coded paths, which are defined with glob patterns. The command attempst to use contents of
       $PATH and $MANPATH environment variables as default search path.  The easiest way to know what paths are  in  use  is  to  add  -l  listing
       option.	Effects of the -B, -M, and -S are display with -l.

AVAILABILITY

       The  whereis  command  is  part	of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
       /util-linux/>.
