Power Script .ksh to decrypt .gpg(passphrase)
Hi all,

i have to make a script in shell unix that decrypt a file .gpg ang through out in the same directory the decypted file.

Well, the problem is to put in the shell the passphrase.
Here the specifications:
File .gpg: bella.zip.gpg
File output: bella_decr.zip
passphrase: bella_zio

if someone could write me the right code to decrypt that file is terrific.

Thank you.
