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

OptionsDescription
-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 whereisnnmnnunn* 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 filenames; must be used when any of the -B, -M, or -S options are used.

 

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

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