How can I easily get a list of secret key IDs available to the current GnuPG user?

I want a hypothetical command gpg --foo which I can use for:

keyids=$( ( gpg --foo ) )
for keyid in "${keyids[@]}" ; do …

What is the gpg --foo command that will just get me the key IDs for my secret keys?

It takes several seconds to complete, but this works:

gpg --list-secret-keys --with-colons \
    2> /dev/null \
    | grep '^sec:' | cut --delimiter ':' --fields 5

Thanks to @dirkt and @grawity for pieces of this answer.

For version 2.1.15, the following works for me:

gpg --list-secret-keys --keyid-format short | grep sec | cut -d' ' -f 4

I'm not sure if the output format stayed identical among versions, so you may have to adapt the following commands if your version uses a differently formatted output.

    If you want a format that stays identical, use --with-colons.

  • @grawity: I got curious and tried --with-colons, but it looks like you need to do extra mangling for the short form, and I don't know enough to do this reliably - always pick the last 8 chars?

My option is using awk:

gpg --list-secret-keys --with-colons | awk -F: '$1 == "sec" {print $5}'
