Change directory permanently in a bash script

Question

I'm trying to change directory in a called bash script. For this I tried to use cd command. But after the script ends current directory is restoring to position before the script call. I also tried to change PATH variable but it didn't show any effect too. Is there a way to do this?

Answer 1

When you execute a shell script a new shell is started for execution of this script. This shell won't affect its parent processes.

To execute a script in your current shell's context use the source or . commands:

. cd.sh
source cd.sh
