cd doesn t work in my shell script

Question

I'm writing this script.

#!/bin/bash
cd /home/tree/projects/python

I saved this file as proj, added execute permission with chmod, and copied it to /usr/bin. When I call it by: proj, it does nothing. 

Am I doing something wrong?

Answer 1

One way to get around this is to use an alias:

alias proj="cd /home/tree/projects/python"

You can also run the script in your current process with the "dot" command:

. proj
