Unix command questions

[SoundTheSurrender]

How would I go about making a alias that would deal with two commands?

For example, every time I use the rm command, I need to have a file deletion confirmation work after it.

So when I delete something, it confirms it.

another question is when I do

ls -l udir it doesn't display the permissions of that folder. all it does is

idnumber@lx:~$ ls -l udir
total 12
-rw-r--r-- 1 idnumber student 21 2007-09-23 18:03 file
-rw-r--r-- 1 idnumber student 21 2007-09-23 18:03 file1
-rw-r--r-- 1 idnumber student 21 2007-09-23 18:03 file2


thanks

If your box is using the GNU tools then 'rm -i' will prompt you before all deletions unless you use -f to force it.
'ls -d' will tell ls that you want the directory itself and not it's contents.

Get comfortable with reading man pages, it'll save you a lot of time.

Creating aliases is a little bit different depending on the shell you're using. But basically, try 'man alias'. You can say: alias rm='rm -i'
