NAME

       whatis - display a one-line summary about a keyword

SYNOPSIS

       whatis command...

DESCRIPTION

       whatis  looks  up  a  given  command  and displays the header line from the manual section. You can then run the man(1) command to get more
       information. If the line starts name(section)... you can do man -ssection name to get the documentation for it.	Try whatis ed and then you
       should do man -s 1 ed to get the manual page for ed(1).

       whatis is actually just the -f option to the man(1) command.

       whatis uses the /usr/share/man/windex database.	This database is created by catman(1M). If this database does not exist, whatis will fail.
