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

You need no script, only set the correct option and create an environment variable.

shopt -s cdable_vars

in your ~/.bashrc allows to cd to the content of environment variables.

Create such an environment variable:

export myjava="/home/tree/projects/java"

and you can use:

cd myjava

Other alternatives.
