can be replaced with a single awk script:
$gas --version | awk '{ gsub(/[.]/, " ", $NF) $0 = $NF printf "%02d%02d\n", $1, $2 exit }'
That looks much longer and we call this once so a few execs is noise.
here's a shorter version: $gas --version | awk '{ gsub(/[.]/, " ", $NF); $0 = $NF; printf "%02d%02d\n", $1, $2; exit }' -mike
