Decrypt command in SM69

Hello,

I've created a command in SM69 and had given Operation System Command as gpg -d and enabled additional parameters.

While executing the command am passing my file as /tmp/test.gpg > /tmp/text.txt

But I'm getting error as Can't execute command. No such files or directory.

Do I need to pass key to decrypt while executing from SM69?

Please let me know what command should be given.

Thanks.

Regards,

MB
