Zenity Checkbox extracting Variables

webaccounts · 09-16-2008, 03:45 PM

I'm trying to get certain variables from a zenity script.

I have a code below.

Code:

#!/bin/sh
hello=$(zenity --list --checklist --title "Testing checkbox." --text "Checkbox test." --column "" --column "Nice" False 1st False 2nd False 3rd False 4th False 5th)

If someone picks 1st and 3rd lets say. Then $hello echo's 1st|3rd

How do I create a variable for 1st and one for 3rd? I kinda want to split up that so I can run multiple scripts for each checkbox.

Thanks,
Klesla

You could split them out with "${hello//|/ }" and a for loop or case statement or use an array: 'hello=(${hello//|/ })' and access elements?

Thanks for the reply.

However when I run it with the code hello=(${hello//|/ }), it gives me 1st3rd. How do I have it split the variables with a for or array statement?

Thanks again.

Code:

somethingTo() { echo $@; }
# You could:
for item in ${hello//|/ }; do somethingTo $item; done
# or with an array:
hello=(${hello//|/ }); for (( element = 0 ; element < ${#hello[@]}; element++ )); do somethingTo ${hello[$element]}; done
# or use a case statement instead of somethingTo.
# Maybe looks convoluted at first, but once you get the hang of it it really isn't.
