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.

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

Change directory command (cd)

It is absolutely working fine but as it is not changing the current directory you are saying it is not working. Try to run your script using source command. eg source <script name> <argument>

When u run the script, at time it creates a separate shell and do the operation in that shell and when programm terminates the shell also got killed. If you still have doubt, please let me know.
