APROPOS(1)						      General Commands Manual							APROPOS(1)

NAME
       apropos - locate commands by keyword lookup

SYNOPSIS
       apropos keyword ...

DESCRIPTION
       Apropos	shows which manual sections contain instances of any of the given keywords in their title.  Each word is considered separately and
       case of letters is ignored.  Words which are part of other words are considered; thus, when looking for	compile,  apropos  will  find  all
       instances of `compiler' also.  Try

	      apropos password

       and

	      apropos editor

       If  the	line starts `name(section) ...' you can do `man section name' to get the documentation for it.	Try `apropos format' and then `man
       3s printf' to get the manual on the subroutine printf.

       Apropos is actually just the -k option to the man(1) command.
