Changing directory does not work in shell script

Question

I am stuck in changing the directory in a shell script in linux.

#!/bin/sh
cd /driver

The above does not change the directory. Shell is running in its own context so it can not provide linux terminal with changed drive (into driver)

but if I give cd /driver ls It gives the proper output of ls in driver directory again comes out of driver directory

Can anybody help me to get terminal with actually changed path (into driver).

Answer 1

If you run your script with

./scriptname

you are opening a sub-shell where the commands of the script are executed. Changing directory in that sub-shell has no effect on the working directory of the shell that you call your script from. If instead you type

source ./scriptname

you should get the desired result.

Answer 2

do "source script_name". It will change the directory
