Linux

Most of the things I post here are tested on Debian and/or alpine and that’s about it, since those are my daily drivers.

Message of the Day

All important Debian locations:

  • /etc/motd
  • /etc/motd.d
  • /etc/update-motd.d

Here’s the official Debian motd docs. Import ecerts below:

…motd is generated by pam_motd. pam_motd prints the contents from /run/motd.dynamic and the static (and user editable) content from /etc/motd and /etc/motd.d … pam_motd updates /run/motd.dynamic by executing all files from /etc/update-motd.d

Pretty view markdown

You can use batcat on linux, ccat on mac, and gh repo view if the markdown file is a README.md in a repo.

You can also use this lynx trick:

pandoc README.md | lynx -stdin

apt notes

Thanks to Vaibhav for their solution here for when you get this error:

W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4DEF31B9A9E345C0

It’s THIS command:

# 4DEF31B9A9E345C0 is your KEYID from the above error
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4DEF31B9A9E345C0
