A tiny bash issue

[QwertyManiac]

Can someone tell me why my little script below (To switch the directory via BASH) does nothing on execution?

#!/bin/bash
cd /home/qwerty/Programs/C
#abc.sh

Here's my output: (Actually, its NOTHING)

qwerty@qwerty-workstation:~$ ./abc.sh 
qwerty@qwerty-workstation:~$

I got no clue at all.

And before someone mentions, its chmod +x'ed alright.

The script is alright and the control return to the original directory after the execution of 'cd' command. That means that the directory is switched as desired and after the execution of the script it returns to the original directory!

To verify it, create some file(s) in '/home/qwerty/Programs/C' and then use some other command with it! e.g

#!/bin/bash
cd /home/qwerty/Programs/C
ls

This will switch the directory first, show the contents of that directory and then return the control to the original directory!

Thanks mediator, I understand it now, but ..

Can I switch control to another directory permanently? So that my current terminal directory gets changed to that? That was my actual aim.

Edit: I got my silly solution by creating an alias command, but I'd still like to know the way (if possible) to change the current directory via a script

Try

$ source abc.sh

Instead of

$ ./abc.sh

Oh, didn't know about that command before. Problem solved, thanks mediator and Sykora.

Infact a "." does the job too reg source command:

^Yup, " . abc.sh " also does the job!
