Almost every UNIX system, Linux included, provides a facility known
|
||||
as ``manual pages'', or ``man pages'' for short. These man pages
|
||||
contain online documentation for all of the various system commands,
|
||||
resources, configuration files, and so on.
|
||||
<P>
|
||||
<A NAME=2365> </A>
|
||||
The command used to access man pages is <tt>man</tt>. For example, if
|
||||
you're interested in finding out about the other options of the
|
||||
<tt>ls</tt> command, you can type
|
||||
<P><TT> /home/larry# <em>man ls</em>
|
||||
<P></TT>
|
||||
and the man page for <tt>ls</tt> will be displayed.
|
||||
<P>
|
||||
Unfortunately, most of the man pages out there are written for those
|
||||
who already have some idea of what the command or resource does. For
|
||||
this reason, man pages usually only contain the hardcore technical
|
||||
details of the command, without a lot of tutorial. However, man pages
|
||||
can be an invaluable resource for jogging your memory if you forget
|
||||
the syntax of a command. Man pages will also tell you a lot about
|
||||
the commands which we won't tell you in this book.
|
||||
<P>
|
||||
I suggest that you try <tt>man</tt> for the commands we've already gone
|
||||
over, and whenever I introduce a new command. You'll notice some of
|
||||
these commands won't have man pages. This could be for several reasons.
|
||||
For one, the man pages haven't been written yet (the Linux Documentation
|
||||
Project is responsible for man pages under Linux as well. We are gradually
|
||||
accumulating most of the man pages available for the system). Secondly, the
|
||||
the command might be an internal shell command, or an alias (as discussed in
|
||||
Section <A HREF="node99.html#secshellscmds">3.2.4</A>),
|
||||
in which case it would not have a man page of its own. One example is
|
||||
<tt>cd</tt>, which is a shell internal command. The shell actually processes
|
||||
the <tt>cd</tt>---there is no separate program which contains this command.
|
||||
