As someone who knows next to nothing about Linux but knows his way around a DOS command line, I found Shell Tips to be a useful start. I did see a couple of things I think are errors; they would be in DOS (and I don't mean "/" instead of "\").
The example for using the nano editor uses the pico editor.
* nano : friendly, easy to use file editor (ex: pico /conf/S00user-script : edit the custom options user file)
Under "Putting commands together" one example says:
last > /tmp/lastlogins.tmp
This will print all the current login history to a file called lastlogins.tmp in /root/
I would expect it to put the file in /tmp/. If I'm wrong, that will add to my understanding of Linux.
