Background and Cron Jobs

I will often run this command to make sure all my docker containers are stopped and removed before running docker-compose up. Sometimes when you restart your system, old containers will start back up automatically in the background.

docker stop $(docker ps -aq) && docker rm $(docker ps -aq)

Prerequisites

1. Enable the multilib repository by editing /etc/pacman.conf
2. Install WineHQ and some other optional dependencies:

   $ pacman -Syu wine
   $ pacman -S --asdeps lib32-mpg123 lib32-gnutls {lib32-,}gst-plugins-base-libs \
                        lib32-alsa-plugins lib32-libpulse lib32-openal
   $ yay -S lib32-unixodbc # or your favourite AUR helper

3. We'll install a 64-bit version of iTunes, so no need to set WINEARCH

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
gpg --gen-key
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null`

# check current keys:
gpg --list-secret-keys --keyid-format LONG

# See your gpg public key:
gpg --armor --export YOUR_KEY_ID
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)
