|
Man formats and displays on-line manual pages for commands and topics of A2osX.
|
|
The man shell script looks for a manpage file for the argument (command or topic)
|
|
and if it finds a corresponding file uses more to display the contents. If no
|
|
argument is passed to man, then this page is displayed. If no file is found for
|
|
argument then an error is displayed. Man looks for its man pages in
|
|
${root}usr/share/man.
|
|
|
|
Available man files are:
|
|
|
|
<<<<Put LS of usr/share/man here>>>>>
