Thank you for your suggestion, I tried it with the version of gnupg
that came with Ubuntu, then again with the latest version, but I don't
seem to be getting any output.
What am I doing wrong?
johnicho...@johnicholas-desktop:~$ cat signed_test.asc

test test, a small message for testing

Okay, I am confirming receipt of a small message for testing.

verified_test.asc signed_test.asc

gpg: Good signature from "Someone Somewhere (Fake name for testing)

johnicho...@johnicholas-desktop:~$ cat verified_test.asc
cat: verified_test.asc: No such file or directory
I tried to see if there was a permissions problem using strace, but it
doesn't seem to be calling open or stat on the output file.
johnicho...@johnicholas-desktop:~$ strace -o gpgrun.strace gpg
--verify --output verified_test.asc signed_test.asc
gpg: Signature made Tue 04 Jan 2011 12:05:55 PM EST using DSA key ID 9236A9C1

johnicho...@johnicholas-desktop:~$ grep verified gpgrun.strace
execve("/usr/local/bin/gpg", ["gpg", "--verify", "--output",
"verified_test.asc", "signed_test.asc"], [/* 40 vars */]) = 0
Thank you for your help,
Johnicholas
