BASH variable help!

[master8899]

Hi,

I was making a bash script to do open three programs in one click. I've gotten the variables all done but I can't get it to work. When I run the bash script it won't open the second program until the first one is closed. How do I get it to open the 1st one, then the 2nd, and then the 3rd right after each other?

It would be helpful to see the script, but perhaps you need to use the ampersand (&) character?

program1 &
program2 &
program3 &

This will "background" each of the programs and should stop the shell waiting for them to return a value before proceeding to the next program.

Okey dokey here is the script I have (I think I did it wrong):

#!/bin/bash
JACK="jackd -d alsa is"
QSYNTH="qsynth"
ROSEGARDEN="rosegarden"
$JACK
$QSYNTH
$ROSEGARDEN

Try this,

#!/bin/bash
JACK="jackd -d alsa is &"
QSYNTH="qsynth &"
ROSEGARDEN="rosegarden &"
$JACK
$QSYNTH
$ROSEGARDEN

The ampersands after each of the commands will background the processes as I mentioned in my previous post. Let us know if it works.

smolloy solved the problem, but, might I ask why are you using variables there?

I can't see a purpose behind it if all you are doing is declaring them just to launch the command three lines below.

Ok thanks. It worked with the &. Now I just have one more question. How do I run the script from terminal? I just wanna be able to type something in the terminal command line and then it do what the script says. THANKS!!!

Ok, nevermind about my last post. I have to drag the icon into terminal and push enter. Duh. I forgot. Ok, so thanks for all of your help you guys!!!!! You've made my day!!!!!!!!!
Bring on the dancing bananas!!!!

I didn't know that dragging an icon into a terminal worked like that! Cool!

You could also add the script to your path by moving it to /usr/local/bin, or by creating a soft link to your script in /usr/local/bin.

Or change to the directory containing your script and enter its name preceeded by ./
i.e.

./yourscript.sh
