Re: [FishMonger] reversing a hash

thanks, I tried that but it looks like I need to install something, is there a package or something:

antobbo@antobbo-xps17-ubuntu:~$ perldoc -q 'How do I look up a hash element by value?'
You need to install the perl-doc package to use this program.

Ah sorry I forgot to add this: I have printed both the hashes, the normal one which produced

Lucy Exeter Samantha Oregon Gary Dallas Ian Reading

and the reversed one which gave

Oregon Samantha Exeter Lucy Reading Ian Dallas Gary

so it appears as if reversing a hash swaps the value and keys?!
