     whatis [-d] keyword ...

DESCRIPTION

     plete words.

     The keyword is simply passed to grep(1) allowing for extended regular expression matches.

     MANLOCALES, MANPATH, PATH
	    Used to find the location of the whatis database files. See manpath(1) for additional
	    information.

     PAGER  Program used to display files.  If unset, more -s is used.

DIAGNOSTICS
     The apropos utility exits 0 if a keyword matched and 1 if no keywords are matched or no
     whatis databases are found.
