What is all this? What is your question?

Any why does this look like some sort of homework assignment?

I have been working with my friends in Ledbury and they had asked me some questions regarding some of the Linux commands above. So all of them could see what them I have posted them here.

What a bizarre use of a forum...

Formatting use one of these commands
fdformat
mount
umount

Editing use one of these commands
vi
pico

Hope this helps Mark

I was thinking more like "rude" or maybe "illegal"....
Seriously, klanz: This is not why LQ is here. Even if the rules allow this, you are violating the intent.

All members have their own blog space: http://www.linuxquestions.org/linux/blog/ and I would very much suggest that that would be the best place for this. Or even, maybe your school has some web space you could use?

Why not nano or emacs?

And if you 're just dumping commands on here, why aren't you telling your friends to either read RUTE or get one of the Running Linux or Linux in a Nutshell books? Book reviews are here and I am sure your BFFs would find them useful.

Wonder how you use umount to format a disk. top quality information there... Hope the cheating works out for you.

Also, how do you use pico if pine isn't installed??
