Comment 4 for bug 9349

I think most of the commented out aliases in .bashrc are very useful:

cd.. -> cd ..
First thing I did after finding out about the aliases. Most linux commands are
not that hard to learn, but getting rid of the habit of typing cd.. is almost
impossible. It is also a big cause of confusion when new users are trying to
follow someone other's instructions and think they are doing it right but keep
getting an error message.

ll -> ls -l
l -> ls
Both not really necessairy, but I really missed them when I switched from
Mandrake and didn't know how to use aliases yet.

Also, no matter how much some people will dislike it, newbie's will really
appreciate rm -> rm -i. Just for safety. Not needed for cp or mv, they are not
by far as dangerous as rm. I already know some people who shortly after starting
using the commandline did rm * in the wrong directory, and if you loose some
important documents, this will not be very encouraging to keep using linux.
