Hi,

I've been looking for a command I can use in bash scripts that will do
something like this:

$COMMAND(n[,m...]) (REGEX-1)(REGEX-2)[...] <($FILE)

       (MATCH-n)[(MATCH-m)...]

A recent article talk about it in bash3.0:

if [[ "a,b,c" =~ ^(.).(.) ]]; then echo ok ${BASH_REMATCH[1]} ${BASH_REMATCH[2]} ; fi
