[CentOS] Source keychain credentials in Perl?

Ok, can't do this because end-users will not like the extra step.

Yep, this is what I did.  I have the source ~/.keychain/hostname-sh in
every command now.  This seems the simplest solution for the time
being.

Yes, and for this simple one-off script probably too much trouble to
go parsing the .keychain file.  Its easier to just source it before
each bash command.

Thanks for all your help, Filipe.
