The original command doesn't work for me - does something weird with sed (-r) and xargs (-i) with underscores all over...

This one works in OSX Lion. I haven't tested it anywhere else, but if you have bash, gpg and perl, it should work.

Know a better way?

If you can do better, submit your command here.

What others think

doesn't work for me, I get:

sed: -e expression #1, char 50: Invalid range end

Comment by Ovidiu 200 weeks and 2 days ago

The invalid range is from a-F in the character class. It should read [a-fA-F0-9]{8}. There are quite a few problems with the original version.
