Hi,
I need to know how I'll be able to write a script that can goto a different dir where I don't have access to read,write and execute and also to run a commandline prompt in that dir with one file whose path has to be specified in that command.
Then it would have to be run by a user that does have the proper permissions. If you don't have the access to an account with the proper permissions, then the rest (of your questions on this) is pointless.
