Hallo @jef-n, on my system astyle is complaining that he can't set the correct locale and always print some lines to stderr. Nothing important but because the sterr get redirected to stdout the version check does not work correctly in my case.
Why is this redirect needed?
If the redirect is still needed I would add something like "| tail -n 1 |" to keep only last line which actually contains the version. But I am not sure if it could broke something?
[ $(printf "$($1 --version 2>&1 | tail -n 1 | cut -d ' ' -f4)\\n$min_version" | sort -${SV} | head -n1) = "$min_version" ]
