Hi,
(First time in a GNU mailing list!)
I've already asked this question to my local GNU/Linux user group and in
#grep@Freenode... I'm still confused.
GNU Grep don't have an arg to choose the subexpression. Right?
Stupid e.g.:
echo abcde | grep -o -E 'b([a-z])d'
=> "bcd"
What if I want the first subexpression? ("b")? GNU Grep can't do it. Isn't it?
(Why?)
I actually use GNU Awk, or GNU Bash with $BASH_REMATCH[$n_sub].
Thank you for the clarification!
