If there was one thing that I wish that I knew sooner as a newbie, it
would be "Where in the heck is all the local documentation?" If you're
interested in learning some basic linux commands, such as rpm and yum,
etc. I recommend that you read on.
Use man on the command line:
man <name of command>
I recommended that you do this one first:
Man pages are generally organized in 8 sections, so sometimes articles
with the same heading appear in multiple places. In that case, you can
do the following:
man # <name of command>
The # being 1-8.
To check for articles in all sections with the same name, type:
man -a <name of command>
Oftentimes, man will find a programming related document and not the one
that you want. For example, man has three of them, one in sections 1,
5, and 7. You can use this command to see how many documents there are
and in what sections:
whatis <name of command>
Sometimes you don't know the name of something. You can use the apropos
apropos <name or keyword> | less
If you get an error on either of the above two, run "makewhatis" to
build the man page index.
You can also use info to sometimes find deeper information on something.
Man and info are both available via the GUI help, so you may find that
much easier to use. Don't worry if you don't understand what you are
reading, much of it is often out of scope of what you may be wanting to
do at the time. For example, if I wanted to know how to update a
package without installing over the previous one, I would type "man rpm"
and discover that the -U and -F switches are available for use.
Package documents are found here:
And finally, here is the incredibly large and very informative "bash
command shell bible":
Have fun and happy reading!
