whatis

whatis(1)							   User Commands							 whatis(1)

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 -s section 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.

FILES

       /usr/share/man/windex	       Table of contents and keyword database
