WHEREIS(1) User Commands WHEREIS(1) NAME whereis - locate the binary, source, and manual page files for a com- mand 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 path- name 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 speci- fied by $PATH and $MANPATH. The search restrinctions (options -b, -m and -s) are cumulative and always applied for the next name patterns specified on command line. The first search restrinction resets the search mask. For example whereis -bm ls tr -m gcc searchs for "ls" and "tr" binaries and man pages, and "gcc" man pages only. The options -B, -M and -S resets search paths for the next name pat- terns. For example whereis -m ls -M /usr/share/man/man1 -f cal searchs for "ls" man pages in all default paths, but for "cal" in /usr/share/man/man1 directory only. OPTIONS -b Search for binaries. -m Search for manuals. -s Search 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/>. util-linux March 2013 WHEREIS(1)
