Hi,
How can I test whether a hash is empty or not ?
For e.g: I have reference to a hash , say $preCommand and I get
$preCommands as {} ,
Its an empty hash, but it exists and is also defined.
I need to check whether the hash is empty or not.
Does anyone has any clue ?
Regards,

Try:
unless( keys %$preCommands ) {
...hash is empty...
}
You can use 'keys %hash' ( or if necessary 'scalar keys %hash' ) to
get a count of the number of hash elements just like @array for arrays.
