[Sheflug] quick bash question



Hi folks,

I'm trying to run various rDNS (PTR) lookups from command line. My
shell-foo is very poor. Can someone help?

I know the hostname I want to lookup - e.g. mail.lug.org.uk and want
to get the PTR record in one line and the shortest number of
key-strokes as possible.

I can get the IP in one command:

host mail.lug.org.uk

and get the PTR record in another:

dig -x 217.147.93.68

but have no idea how to combine the two or pipe output from the first
to the second. I can probably get it in a single command but would be
interested in the solution anyway.

Thanks

Chris
