When I import my GPG keys, I get a response back:
gpg: key LOL12345: public key "John Doe (Developer) <john@doe.com>" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
I would very much like to extract the key’s ID LOL12345
.
The command I run that returns the output is as follows:
gpg --import "public.key"

Try to use grep:
yourCommand | grep -Po -m 1 'gpg: key Kw+'
-P
use perl regex style.
-o
print only the matched part.
-m 1
exit after the first match. This will ensure, that the key is not printed multiple times.
K
once matched, forget the matched part left of K
.
w+
Match as many alphanumeric characters as possible.
