apropos(1)						      General Commands Manual							apropos(1)

Name
       apropos - locate commands by keyword lookup

Syntax
       apropos keyword...

Description
       The  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.

       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:
       apropos format

       To then access the reference page for the printf subroutine that you see listed, type:
       man 3s printf

       The command is actually just the -k option to the command.
