Shell Programming and Scripting

Please put code between [code] tags.

dirperm=$(ls -ld $(echo $user | awk -F: '{ print $6 }') | awk -F ' ' '{print $3}')

I don't understand exactly what you are trying to do, but that looks far more complicated than it need be. For example, couldn't part of that be done more easily with:

Code:

eval "dir=~$user"

#echo $username
if [ "$username" == "$dirperm" ]

The == operator is not standard.

then
echo $username [PASS]
else
if [ -z "$dirperm" ]
then
echo $username [FAIL - Directory Does not Exists!]
else
echo $username [FAIL]

What do you mean by "invalid" and where do you test for that?

What do you mean by "invalid"? If you want to check whether it exists, use test -d.
