@edward torvalds - Thanks for this. You are quite right, although I don't fully understand why yet. I've fixed my mistake. ;)

@MarcusJuniusBrutus - Yes, you're right. I think the solution is to remove a #, e.g. for f in find a/* ! -type l;do echo $f b/${f#*/};done. I don't have time to test this right now though. Let me know if that works.

comment Facility on AIX to ZIP a list of files
There are various internet zip tools. This one runs in a browser (it's Java), so no files are uploaded anywhere. Would that help?

comment Check a range of IP addresses to see if a host is active
Note that ping gives only the most rudimentary indication of 'aliveness'. Which is why things like Nagios exist, to allow you to check specific services or the running state on the machine. A ping check is a bit like checking a person is breathing; they could nevertheless be in a coma and not able to perform any function. It is entirely possible for a server to respond to pings and be otherwise totally unresponsive.

Hmm. This smells like script kiddie to me. Why do you need to do this?
