Can you not EVER try to do any of this on your own?? EVERY thread you've ever opened, you ask other folks to do your scripting/work for you. It would be nice if you showed some effort on your part, every now and then.
EDIT: Per the OP's private comment: You have said you are "new to shell" in EVERY thread. You can only be "new", if you don't ever TRY to do it yourself and learn.
