Took me a while to realise this was running an awk script for output
slection but using grep for regex based line selection. Awk can do
both of these things just fine, and the result is much more
readable:
group_names() {
awk '/^[[:lower:][:digit:]_]/ {
if ($1 != "Group" && $2 != "Name:" && $1 != "all")
printf("%s\n", $1);
}' doc/group-names.txt
}
$ awk '/^[[:lower:][:digit:]_]/ { if ($1 != "Group" && $2 != "Name:" && $1 != "all") printf("%s\n", $1); }' t.t
