Need Help with a Bash/Perl Script

[BIGtrouble77]

I basically need to write a script that will execute the following:
metacity --replace
wine "myprogram"
on exit compiz --replace


I have no problem doing the first two steps, but I'm not sure how to get it to execute the compiz --replace on exit. Any suggestions?

Just try this:

#!/bin/bash

metacity --replace
wine "my program"
compiz --replace

When "my program" exits it will execute the next line, which is 'compiz --replace'

Hope that helps you,

that is not always the case as 'my program' could be a launcher which will then run the real application.

I'm no expert at scripting, but I think this works. HIH.

#!/bin/bash
function procnumber () {
    echo `ps ax | awk -v var=$1 '{if($1==var){printf("%d", $1)}}'`
}

metacity --replace
wine "my program"
PID=$!

while [ "$PID" != "" ]; do
    PID=`procnumber $PID` 
    sleep 2
done

compiz --replace

@slavik
Yes you are correct on that although the OP did not specify what "my program" was, it may or may not work for him

Thanks guys. I should have played with the actual script a bit more before I posted... Turns out running wine and then replace --compiz works perfectly, but having it change over to metacity first is an issue.

The problem is that the metacity process never ends so my wine instruction can't start. Somehow I need to run the metacity --replace independently of the other commands so that they are not waiting for the process to end before they execute.

The reason I have to do this is because I have a game I'm running through wine that doesn't like compiz. If I just kill compiz and don't load metacity my keyboard stops working 50% of the time, but the game seems to otherwise work fine.

unutbu, I'll try your suggestion when I get home later today.

Try this:

#!/bin/bash

metacity --replace &
wine "my program"
compiz --replace

glad you're getting there
