- locate commands by keyword lookup
apropos keyword...
The apropos utility displays the manual page name, section number, subsection name, the keyword, and a short description for each manual page that contains keyword.
This information is contained in the index files that are either automatically created by an SMF service as described in man(1) and man(5), or manually created using catman(1M) with -w option.
Each word is considered separately and the case of letters is ignored. Stemming on English words and section matching are also supported. Words which are part of other words are considered. For example, when looking for compile, apropos finds all instances of compiler as well. .
As apropos is simply the -k option to the man(1) command, see man(1) for more details.
示例 1 Finding a Manual Page with a Name Line Containing keyword
Try
example% apropos password
and
example% apropos editor
If the line starts filename(section) ..., you can run
man -s section filename
to display the manual page for filename.
示例 2 Finding a Manual Page for the printf() Subroutine
Try
example% apropos format
and then
example% man -s 3s printf
to get the manual page on the subroutine printf().
