Connecting to the wrong server

[Meme transcription:]

– 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.

Here we simply have a tool that on dangerous commands like power off or reboot asks for the host name of the machine in question. Didn’t stop me from accidentally rebooting a machine once, but no matter

sounds interesting. do you have the name of the tool or is it a custom script

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.

Oh, so we're Winkelschleifern prompts now?

As normal user, the username is also green, and the # is a $

Shell colors change the game really. I did this at work; when I'm on the admin server my prompt is rainbow, other servers black (I use a solarized light terminal). It has saved me so many times.

this is honestly my worst fear as someone who suffers from ocd and compulsive checking

Man it's late here but I just don't get it. Isn't tmux enough to separate sessions then you just look before you run something like this?
