Hi,
I have used Data::Dumper to get the hash. I can test myself that the
hash is empty.
But how can test in by script that the hash is empty?

HI,
You can use Data::Dumper And print the hash reference as,
use Data::Dumper
print Dumper ($preCommands);
If the output is VAR1= {};
Then there are no entries in the has tables

Subject: Check empty hash
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,
Suvajit
