whereis — locate the binary, source, and manual page files for a command
whereis [options] [
−f ] name...
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
The search restrictions (options
−s) are cumulative and apply to the
patterns on the command line. Any new search restriction
resets the search mask. For example,
whereis -bm ls tr -m gcc
searches for "ls" and "tr" binaries and man pages, and for "gcc" man pages only.
−S reset search paths for the
patterns. For example,
whereis -m ls -M /usr/share/man/man1 -f cal
searches for "ls" man pages in all default paths, but for "cal" in the /usr/share/man/man1 directory only.
Search for binaries.
Search for manuals.
Search for sources.
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.
Limit the places where whereis searches for binaries, by a whitespace-separated list of directories.
Limit the places where whereis searches for manuals and documentation in Info format, by a whitespace-separated list of directories.
Limit the places where whereis searches for sources, by a whitespace-separated list of directories.
Terminates the directory list and signals the start
of filenames. It must be used when any of the
−S options is used.
Output the list of effective lookup paths that
is using. When none of
−S is specified, the option will
output the hard-coded paths that the command was able
to find on the system.
To find all files in
/usr/bin which are not documented in
/usr/man/man1 or have no source
whereis −u −ms −M /usr/man/man1 −S /usr/src −f *
By default whereis tries to find files
from hard-coded paths, which are defined with glob patterns.
The command attempts to use the contents of
variables as default search path. The easiest way to know
what paths are in use is to add the
−l listing option. Effects of the
−S are displayed with
The whereis command is part of the util-linux package and is available from Linux Kernel Archive
