find ~/.mozilla/firefox -type f -maxdepth 2 -name prefs.js | while read f; <-- this line is needed because you cannot define the actual directory of prefs.js since it is actually saved in ~/mozilla/firefox/[RANDOM NAMe.Default]/pref.js
Right, we want to catch all profiles. My first idea was to parse the profiles.ini. This may be crude but faster.

so besides the way the file is found, it should be the same right? grep to find the line, and sed to substitute (arg1) with (arg2) in that said line?
Well in essence the grep is only there to see if there is a string occurrance. If it's not it would be futile (inefficient) to sed anyway.

Am i close
Yes, well done.

can anyone give me some guides to this bash script stuff besides that howto, coz I think this is where is the real LINUX power is, and I would like to learn how to use it constructively.

Code:

function help() { echo "Bash scripting guides:
http://www.tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html 
http://www.tldp.org/LDP/Bash-Beginners-Guide/html/index.html 
http://www.tldp.org/LDP/abs/html/"; }

#!/bin/sh

esac
exit 0

i wrote that, and get this error:
/home/ndr008/bin/proxy.sh: line 12: ~/.kde/share/config/kioslaverc: No such file or directory

BUT ~/.kde/share/config/kioslaverc exists....

ok guys, i changed it to this:

#!/bin/sh
# set -xe

case "$1" in
on) find ~/.mozilla/firefox -type f -maxdepth 2 -name prefs.js | while read f; do
{ sed "s|network.proxy.type\", 0|network.proxy.type\", 2|g" \
"${f}" > "${f}.tmp" && mv -f "${f}.tmp" "${f}"; }

find ~/.kde/share/config/kioslaverc | while read f; do
{ sed "s|ProxyType=0|ProxyType=2|g" "${f}" > "${f}" > "${f}.tmp" \
&& mv -f "${f}.tmp" "${f}"; }

done;;

off) find ~/.mozilla/firefox -type f -maxdepth 2 -name prefs.js | while read f; do
{ sed "s|network.proxy.type\", 2|network.proxy.type\", 0|g" \
"${f}" > "${f}.tmp" && mv -f "${f}.tmp" "${f}"; }

find ~/.kde/share/config/kioslaverc | while read f; do
sed "s|ProxyType=2|ProxyType=0|g" "${f}" > "${f}" > "${f}.tmp" \
&& mv -f "${f}.tmp" "${f}";

done;;

esac
exit 0

and now get:

/home/ndr008/bin/proxy.sh: line 13: syntax error near unexpected token `;;'
/home/ndr008/bin/proxy.sh: line 13: `done;;'

thanks, now i understood that the 'done' wasn't part of the case statement and solved the problem
