whereis - Unix, Linux Command



NAME

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

SYNOPSIS

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

DESCRIPTION

whereis locates source/binary and manuals sections for specified files. 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 a list of standard Linux places.

OPTIONS

TagDescription
-bSearch only for binaries.
-mSearch only for manual sections.
-sSearch only for sources.
-uSearch 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.
-BChange or otherwise limit the places where whereis searches for binaries.
-MChange or otherwise limit the places where whereis searches for manual sections.
-SChange or otherwise limit the places where whereis searches for sources.
-fTerminate 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.

EXAMPLE

Find all files in /usr/bin which are not documented in /usr/man/man1 with source in /usr/src:
TagDescription
example% cd /usr/bin
example% whereis -u -M /usr/man/man1 -S /usr/src -f *

FILES

TagDescription
/{bin,sbin,etc}
/usr/{lib,bin,old,new,local,games,include,etc,src,man,sbin,
X386,TeX,g++-include}
/usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}
 

SEE ALSO

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.
