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/>.

NAME

       whereis - Locates files for programs

SYNOPSIS

       whereis [-bms] [-u] [-BMS directory... -f] program...

       The whereis command locates source, binary, and/or reference page files for the specified program program.

OPTIONS

       The -b, -m, and -s options can be used in combination to restrict the search.  Searches for an executable program.  Searches for the refer-
       ence page for a program.  Searches for the sources of a program.

       Use the -B, -M, and -S options to change or limit the places whereis searches.  Specifies the binary directories to search.  Specifies  the
       reference page directories to search.  Specifies the source directories to search.

       The  other options that can be used with whereis are as follows: Terminates the last directory list and signals the start of program names.
       Used with other options to indicate when there is no file for program in the default or specified directory or directories (source, binary,
       or reference page).

DESCRIPTION

       The  whereis  program  locates source, binary, and reference pages for the specified programs.  When looking for a match, the program names
       are stripped of leading pathname components and any trailing extensions of the form (for example, s.  resulting from the use of the  Source
       Code Control System see sccs(1), are also handled.

       The default directories searched by the whereis command are as follows: /etc /etc/nls /sbin /usr/bin /usr/lbin /usr/lbin/spell /usr/ccs/lib
       /usr/lib /usr/local /usr/hosts /usr/sbin

EXAMPLES

       To find files matching cat in the default source, binary, and reference directories, enter: whereis cat To search for reference	pages  for
       app13  in the directory /usr/local/man, enter: whereis -M /usr/local/man -f -f appl3 To find the programs in /usr/bin that do not have ref-
       erence pages in /usr/share/man/man1 with source files in /usr/src/cmd, enter: whereis -u -M /usr/share/man/man1 
	       -S /usr/src/cmd -f /usr/bin/* To find which files in the current directory either have no reference pages in the default  reference
       directories or have more than one, enter: whereis -m -u *

FILES

       Default binary directories.  Default binary directories.  Default reference directories.  Default source directories.
