      NAME
           whereis - locate source, binary, and or manual for program

      SYNTAX
           whereis [ -sbm ] [ -u ] [ -SBM dir ...  -f ] name ...

      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'', e.g. ``.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 places.  If any of the -b, -s
           or -m flags are given then whereis searches only for
           binaries, sources or manual sections respectively (or any
           two thereof).  The -u flag may be used to 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.

           Finally, the -B -M and -S flags may be used to change or
           otherwise limit the places where whereis searches.  The -f
           file flags is used to terminate the last such directory list
           and signal the start of file names.

      EXAMPLE
           The following finds all the files in /usr/bin which are not
           documented in /usr/man/man1 with source in /usr/src/cmd:

                cd /usr/ucb
                whereis -u -M /usr/man/man1 -S /usr/src/cmd -f *

      FILES
           /usr/src/*
           /usr/{doc,man}/*
           /lib, /etc, /usr/{lib,bin,ucb,old,new,local}

      BUGS
           Since the program uses chdir(2) to run faster, pathnames
           given with the -M -S and -B must be full; i.e. they must
           begin with a ``/''.
