in reply to A wrapper script for tmpwatch in Linux written in Perl

system "/usr/bin/ssh $system->{host}#this part doesn't work, o+nly brings back reference";
of course! $system->{host} is a hash reference! you need 
$system->{host}->{$host}

to access the hostname.

    I tried that and it doesn't work because it only enters that part of the if condition, if $host (the machine you are logged into at that time, which I have set with $host =`hostname`) doesn't equal $system->{host} 
    if ( not $system->{host}{$host})

    I need to be able to dreference $system->{host} so it will come up with the name of the hostname, but I don't think that will work because the hostname is the key rather than the value. I think I might have to change my hash. Thanks for your help anyway.
