Shell Programming and Scripting

Hi i am a total noob at shell scripting. i was wondering if somebody could help me with my script.
i want the script to search the dev folder for the burner file
because they are different between distrubutions? as i under stand it.
this i the script.

Code:

#!/bin/bash
echo "Script för att bränna 360 spel med growisofs"
f_pause(){
  read -p "$*"
}

echo "Tryck på enter för att fortsätta!"
f_pause "Eller för att avbryta ctrl-c"
iso=$1
abgx360 -af3 ${iso}
f_pause(){
  read -p "$*"
}

echo "Är allt ok?"
f_pause "Tryck på enter för att fortsätta!"
growisofs -use-the-force-luke=dao -use-the-force-luke=break:1913760  -dvd-compat -speed=4 -Z /dev/dvdrw=${iso}
echo "Tackar för att ni använt mitt script!:p"

where it says dvdrw now i want the script to probe for the file
and exchange it with the one the distrubution is using

Cheers
ps. sorry for bad english.

why are you declaring f_pause twice? declare it once, then just use it, like a command.

Where do you expect $1 to come from? A commandline parameter or the read?

i use it like this. ./test.sh test.iso
so thats a commandline parameter right?

Actually i dont relly know what every thing does or how to really use them.
as i stated in the title i am a total noob on shell scripting.

i just found something thru google and it worked.
but if somebody thinks that it should be better another way
feel free to change it to youre liking and post it.

i tried to make the script break if abgx360 encounterd
any problems. but couldet find any helpful information.
to make i do that.

cheers

Yes.

Code:

if ! abgx360 -af3 ${iso}
then
        echo "problem"
        exit 1
fi

Thank you.
