*For the sake of illustration of filtering through external command*:
It's OK to:
head /etc/group | awk '{print $0 | "cut -d':' -f1";}'
or,
head /etc/group | awk '{ "echo " $0 | getline result ; print result}'
Any way to filter through external command to variable, somewhat like:
head /etc/group | awk '{print $0 | "cut -d':' -f1" | getline result ;}'
Any way to make it works?
Thanks
