WHEREIS(1)             DragonFly General Commands Manual            WHEREIS(1)


NAME

     whereis -- locate programs


SYNOPSIS

     whereis [-abmqsux] [-BMS dir ... -f] program ...


DESCRIPTION

     The whereis utility checks the standard binary, manual page, and source
     directories for the specified programs, printing out the paths of any it
     finds.  The supplied program names are first stripped of leading path
     name components, any single trailing extension added by gzip(1),
     compress(1), or bzip2(1), and the leading `s.' or trailing `,v' from a
     source code control system.

     The default path searched is the string returned by the sysctl(8) utility
     for the user.cs_path string, with /usr/libexec, /usr/games and the
     current user's $PATH appended.  Manual pages are searched by default
     along the $MANPATH.  Program sources are located in a list of known
     standard places, including all the subdirectories of /usr/src and
     /usr/dports.

     The following options are available:

     -B      Specify directories to search for binaries.  Requires the -f
             option.

     -M      Specify directories to search for manual pages.  Requires the -f
             option.

     -S      Specify directories to search for program sources.  Requires the
             -f option.

     -a      Report all matches instead of only the first of each requested
             type.

     -b      Search for binaries.

     -f      Delimits the list of directories after the -B, -M, or -S options,
             and indicates the beginning of the program list.

     -m      Search for manual pages.

     -q      (``quiet'').  Suppress the output of the utility name in front of
             the normal output line.  This can become handy for use in a
             backquote substitution of a shell command line, see EXAMPLES.

     -s      Search for source directories.

     -u      Search for ``unusual'' entries.  A file is said to be unusual if
             it does not have at least one entry of each requested type.  Only
             the name of the unusual entry is printed.

     -x      Do not use ``expensive'' tools when searching for source
             directories.  Normally, after unsuccessfully searching all the
             first-level subdirectories of the source directory list, whereis
             will ask locate(1) to find the entry on its behalf.  Since this
             can take much longer, it can be turned off with -x.


EXAMPLES

     The following finds all utilities under /usr/bin that do not have
     documentation:

           whereis -m -u /usr/bin/*

     Change to the source code directory of ls(1):

           cd `whereis -sq ls`


SEE ALSO

     find(1), locate(1), man(1), which(1), sysctl(8)


HISTORY

     The whereis utility appeared in 3.0BSD.  This version re-implements the
     historical functionality that was lost in 4.4BSD.


AUTHORS

     This implementation of the whereis command was written by Jorg Wunsch.


BUGS

     This re-implementation of the whereis utility is not bug-for-bug
     compatible with historical versions.  It is believed to be compatible
     with the version that was shipping with FreeBSD 2.2 through FreeBSD 4.5
     though.

     The whereis utility can report some unrelated source entries when the -a
     option is specified.
