in reply to `hostname -s`

$HOSTNAME = `hostname -s`;

$HOSTNAME includes "\n". Chomp it.

Update: Here's a way to see what's happening:

prompt$ perl -e '$HOSTNAME = `hostname -s`; print $HOSTNAME;' | od -c

    Ah! Yes of course! I tried out the update you included. That is interesting that it includes the "\n". I fixed the code

    chomp($HOSTNAME = `hostname -s`);

    and it works great now! Tried it on all three servers and it was successful. I'm going now to relay the fix to my coworker. Thanks for your help!

[thepkd]: $aohoaoh ->{'foo'} has to be dereferenced to access its contents right?
[thepkd]: sorry. i mean $aohoaoh[0]
[GotToBTru]: $aohoaoh is an array reference tho
[thepkd]: some guy was suggesting $aohoaoh[0]->{'foo '}[0]->{}. This wouldnt work.
[GotToBTru]: you're mixing notation there I think
[GotToBTru]: $aohoaoh->[0] is a hash reference, so $aohoaoh->[0]->{ key1} would work
