Why I can't change directories using “cd”?

Question

I\'m trying to write a small script to change the current directory to my project directory:

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

I save

Answer 1

This should do what you want. Change to the directory of interest (from within the script), and then spawn a new bash shell.

#!/bin/bash

# saved as mov_dir.sh
cd ~/mt/v3/rt_linux-rt-tools/
bash

If you run this, it will take you to the directory of interest and when you exit it it will bring you back to the original place.

root@intel-corei7-64:~# ./mov_dir.sh

root@intel-corei7-64:~/mt/v3/rt_linux-rt-tools# exit
root@intel-corei7-64:~#

This will even take you to back to your original directory when you exit (CTRL+d)
