Doing that, maybe with some inline concatenation to make a new structure, and this are about all I use:

Printing based on another field, example gets UIDs >= 1000:

    awk -F: '$3 >= 1000 {print $0}' /etc/passwd

It can do plenty of magic, but knowing how to pull fields, concat them together, and select based on them cover like 99% of the things I hope to do with it
