Online Manual Pages

Many times in this book, I refer to the online manual pages supplied with Linux. You can get the online manual page for a command by issuing man command_name. You can view an online manual page from a specific section by specifying the section number. To view the signal man page in section seven, you would issue the following command:

# man 7 signal

This produces the signal(7) man page. If you were to type just man signal, the signal(2) man page would be produced; that is, the man page for signal in section 2 would be shown.

Also, see /usr/share/doc where most Linx documentation is kept. /usr/ share/doc/ <pkg-name> contains information about packages.
