.SH Description
.NXR "apropos command"
.NXA "man command" "apropos command"
.NXR "online information" "accessing"
The
.PN apropos
command
shows which manual sections contain instances of any of the given
keywords in their title.
Each word is considered separately and the case of letters is ignored.
Words that are part of other words are listed.  Thus, looking for
the word compile hits all instances of `compiler' also.
.PP
If the line starts `name(section) ...' you can do
`man section name' to get the documentation for it.
The following command line lists all commands that have to
do with formatting:
.EX
apropos format
.EE
.PP  
To then access the reference page for the
.I printf
subroutine that you see listed, type:
.EX
man 3s printf
.EE
.PP
The
.PN apropos
command is actually just the
.B \-k
option to the
.PN man
command.
