– Hey, why is the shell prompt on the production server red now?
– Earlier: me@prod:~$ docker container remove --force the-application

Protip: If you’re used to shutting down your computer via the CLI, make it a habit to use an alias like off.

This way you will never, ever turn off a remote server by accidentally using throwing poweroff at a residual SSH connection.

    If you’re using a descendant of Debian, you will find a line like this in your ~/.bashrc file:

    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$

    The 32m part controls the color of the username. (\u). 1 is red, 2 is green (as seen in the user and host part, \u@\h), 3 (as seen for the directory, \w) is blue.

    You can use this to distinguish different hosts by color.
