It actually does. There are just two things which differ:
- gpg needs to ask for a passphrase. For obvious reasons we do not
want to take the passphrase from stdin by default but use a direct
pty access for this.
- gpg was designed as a replacement for pgp and thus comes with an
extensive tty based user interface. This is indeed not what a Unix
tool should be but it helps the user to get the crypto right.
And different to many Unix tools, gpg keeps state like cron, batch,
mail, and at does.
There are two simple things you need to remember when using gpg in a
1. --batch to avoid all interaction.
2. --with-colons to get a well defined output format. That format is
not good for humans, though.
Well we could have done switching the output format automagically but
that would be rather surprising. If it is used by a script, adding two
extra options for the invocation is not really a bug task.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
