I am trying to write a script that types in the gpg passphrase and I can't get it to work I can get the phassphrase to echo back by doing gpg --passphrase-fd 0 | echo passphrase. Does anyone know how I can do this... Thanks...

It might help if you piped the output of echo into the input of gpg, rather than the other way around!

Perhaps gpg would like to do something useful rather than just read your passphrase - decrypt something for instance?

I am trying to get it to automatically sign the document and encrypt. I am not sure the correct sytax to do this and everything fail. When I put in

gpg --sign --encrypt uid | echo passphras |gpg --passphrase-fd 0

or echo passphrase | gpg --passphrase-fd 0
gpg --sign --encrypt uid

Can you please help

echo "passphrase" | gpg -se -u "sign_with_uid" -r "encrypt_for_uid" --passphrase-fd 0 filename
