Command to change number of workspaces

I'm currently using Ubuntu GNU/Linux with compiz.

I'd like to have a hotkey to change the number of workspaces, just by increasing the width of my desktop by adding or removing 1 workspace at a time. So...how do I do it?

I did more research on my own, and found the key in gconf that has the hsize of my desktop, it was:
/apps/compiz/general/screen0/options/hsize

If you change it does that do what you wanted?

It does, right now I'm trying to figure out how to write a command that will increment or decrement it. I have very little experience in actual scripting...
I know I can use gconftool to get or set keys, but I don't actually know how to

Code:

value = get foo

set foo = value-1

Code:

#!/bin/bash



file=/apps/compiz/general/screen0/options/hsize



case $1 in

    up | down )

        ;;

    * )

        echo "Usage: ${0##*/} up | down" >&2

        builtin exit 1

esac



read n_workspaces < $file

if [[ $1 = up ]]; then

    let n_workspaces++

else

    let n_workspaces--

    [[ $n_workspaces -lt 1 ]] && let n_workspaces=1

fi

echo $n_workspaces > $file

EDIT: to put the output from a command into a variable

Code:

var=$( some command 2>&1 )

The 2>&1 is only necessary if the command writes to standard error instead of standard out.

That's great thank you so much! One of my friends also whipped up this:

Code:

#!/usr/bin/env bash

# the backticks tell bash to store the shell output of the enclosed command into the variable "number"

number=`gconftool --get /apps/compiz/general/screen0/options/hsize`

# the $(()) syntax apparently tells bash to do math on the stuff inside

numberInc=$(($number + 1))

# this is just running the right command, but pasting the calculated number onto the end of the command line

gconftool --type Integer --set /apps/compiz/general/screen0/options/hsize $numberInc

This one seems a little simpler, but thank you for taking the time to write that for me.
