you must be specifying only the directory name. Are you giving the whole path?
You need to give the whole path with your current code in the script.

This is because the script runs in a subshell, and once the script exits, it comes to your working dir where you were.

You should specify the directory path and folder name before issue the cd command (before change the current directory)

i did give the whole path..

e.g.: i run my script from /home/blah/test

when i run the script..

i enter /home/blah as the input

the input shows "cd /home/blah"

when the script finishes, i run "PWD" command and i'm still at /home/blah/test instead of /home/blah
