[Gedare Bloom]

a few one-liners to try out, here's what I get (Ubuntu 18.04):
$  perl --version 2>&1 | grep version | sed -e 's/.*(v\(.*\)).*/\1/'
5.26.1
$   perl --version 2>&1 | grep version | sed -e 's/.*perl \([0-9]*\),.*/\1/'
5
$    perl --version 2>&1 | grep version | sed -e 's/.*version \([0-9]*\),.*/\1/'
26
