Maybe you should try use a text editor first and learn how Linux works mhmm?
Oh mai gawd can i have a green hat now when i just told you how to open a fileCode:~ bt # nano etter.conf
with a texteditor that is built-in in BackTrack and of course also Slackware?
PS: You use F2 or CTRL+X to save your edited file. CTRL+X will just exit if you didn't edit it.
