Alice Ryhl's questions

Here's the situation, I have a PGP key I generated a long time ago and I have lost my private key. However I have a revocation certificate on my USB drive and I would like to revoke the key.

After looking on the internet I found this solution

$ gpg --import /path/to/usb/revocert-01324567.asc
gpg: key 01324567: no public key - can't apply revocation certificate
gpg: Total number processed: 1

I'm unsure how to download my public key from the keyserver, and how to upload it. Help would be appreciated.

I would like to run ls and exclude certain files in the output.

When I run the following command, I get all files, each on a separate line:

$ ls -1
file1
file2
file3
temp

I would like to run this command in a way so that it shows:

$ ls -1 <insert magic here> temp
file1
file2
file3
