Re: [PLUG] Awk *language*: was Win Subsystem for Linux2 broken

You can do the same thing with the cut command but I tend to use awk the same way you do here all the time.  Sadly I should know how to do this in Powershell but can't think of it right now.

Main thing I do with awk is use it to pull one field out of a record.

Stuff like:
zfs list -t snapshot -r offline1/storage | awk '{ print $1}' | tail -n
+2 | xargs -n 1 zfs destroy

This pulls up a list of snapshots, grabs just the first field of each,
strips the headers, then deletes each one.

Is there an easier way to pull one field (not necessarily the first)
out of a list?
