It would never have occured to me to cut fields out of order.

Or... "Hmm, I only want a few fields from the input,so I'll write a tool to crop the input on demand." Once you realise that cut _cuts_ stuff it's all obvious. It doesn't start with a blank output and fill stuff in, it starts with a filled in line and cuts stuff out. | i'm just curious what kind of thinking went into doing something so | non-intuitive.

And again: cut is not filling things in. It's cutting things out. -- Cameron Simpson <cs@xxxxxxxxxx> DoD#743 http://www.cskk.ezoshosting.com/cs/ Peeve: Going to our favorite breakfast place, only to find that they were hit by a car...AND WE MISSED IT. - Don Baldwin, <donb@xxxxxxxxxx> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
