The same way you would for a normal hash: keys.
%myhash = (
client19 => [
'client2',
'client5',
'client7',
],
client20 => [
'client3',
'client4',
'client8',
],
);
{
local $"=', '; #set the LIST SEPARATOR var to ', '
#print each key followed by the data it points to
print "$_ => @{$myhash{$_}}\n" foreach keys %myhash;
}
