Text editors
There are many text editors that you may choose from. Usually (not always) mc (Midnight Commander)comes with most distro because:

1)It's easy to use/learn.

2)You can install .deb and .rpm with mc.

3)It does ftp.

4)It's the same whether using a GUI or in text mode.

3) It's more nutritious than corn flakes.

Look at your Kmenu(If you use KDE of course). There should be a menu of text editors. kedit, xedit, kate (very excellent) emacs and so on. You can use any of them. Hell you can use Konqueror and default kedit for that matter just like M$ exploder. That's actually very easy to use.

*5 star tip-o-the-day*
Open a term,
konqueror
right click on any file/folder>Properties>Permissions tab
--------->If launched as root a very dangerous tool!!
It would be good to get away from using the start menu so much anyway-learn to launch apps from the CLI-many of them you can guess correctly. You can right click on the desktop>run program>blah and away you go. But the CLI is alot faster than a menu.

Alternatively, if you have a term open (I always have several) you can just enter the name of the text editor, the path and filename and away you go like this:

mcedit /etc/X11/XF86Config-4

That can be translated like this:

mc (use Midnight Commander) edit (to edit) /etc/X11/ (the path to the file) XF86Config-4 (the filename).

You can also do this:

cd /etc/X11
mcedit XF86Config-4

It's the same thing. You just don't need to provide a path because you are already there. You are said to be "in that directory". How do you know which directory you're in?

pwd

Present Working Directory

What if you don't know what the exact name of the file is?

cd /etc/X11
ls

Better yet:
The TAB key completes entries for you. Just type the beginnig letters of a path or file and hit TAB- you'll see.

To start a service on boot add a script to /etc/init.d and do:
sudo update-rc.d <scriptname> defaults
