to decrypt my "INPUTFILE". When I run the script, it pauses and wait
for the passphrase. If I enter the passphrase, the script goes
through well. If I hit enter without the right passphrase, the script
complains about not having the right passphrase.
How can I run this script in silent mode, feed the passphrase to it
automatically? I am trying not to interact with the script during its
Thanks - Jane
