> Can you please cite examples? I've never seen any software do that. With `gpg --verify` you can specify which file descriptor you want it to output to. I've previously used it to ensure a file is verified by a key that is trusted ultimate. Something that otherwise requires outputting to a file. Something like this: tmpfifo="$(mktemp -u -t gpgverify.XXXXXXXXX)" gpg --status-fd 3 --batch --verify "$sigFile" "$file" 3>"$tmpfifo" grep -Eq '^\[GNUPG:] TRUST_(ULTIMATE|FULLY)' "$tmpfifo" || exit 1 GPG also has `--passphrase-fd`. Possibly other option too.
