WHEREIS(1)                                                       User Commands                                                      WHEREIS(1)

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

       -b     Search only for binaries.

       -m     Search only for manual sections.

       -s     Search only for sources.

       -u     Search  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.

       -B     Change or otherwise limit the places where whereis searches for binaries.

       -M     Change or otherwise limit the places where whereis searches for manual sections.

       -S     Change or otherwise limit the places where whereis searches for sources.

       -f     Terminate 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:

              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}

       /usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}

SEE ALSO

       chdir(2V)

BUGS

       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.

AVAILABILITY

       The whereis command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
