I know how you felt. Many years ago when I was a junior working in a casual game company, I were to add a bunch of credits to a poker player (fake money). I forget the where in the SQL clause and added credits to every player in our database. Lucky me it was an add and not a set and I could revert it. Another time I was going to shutdown my pc (a debian box) using "shutdown -h now" and totally forgot that I was in a ssh session to our main game server. I had to call the tech support overseas and tell him to physically turn on the server...
molly-guard -- looks great. I've always aliased my commands so if I accidentally type 'po' while in an ssh session on a production server then it complains. On my local dev box, 'po' is just quicker for me to power off the box. It has saved me at least once.
At one job I went with this scheme for terminal background color: green screen for development, blue for testing, yellow for stage / system test, and red for production. This saved a lot of problems because I knew to be very careful when typing in the red.
Interessting, I have been the only guy in my team who had the exact opposite colours. Green was production and red was testing (i didn't do any dev work, so). I guess that came from me being from produciton. But I should have payed more attention when working with other people on my machine, in hindsight... Luckily, nothing bad ever happened!
I liked a green screen (too much time spent with old terminals) and blue was ok to type on but not as nice . I went with the yellow (warning) and red (serious warning) because they are not very comfortable to type on and most people get the "alert" status given Star Trek.
I have done this on a few servers but found that it always screws up formatting of the lines in bash when they are long and you are hitting up and going back through the history.
Did you change the $PS1 variable? Can you share your config?
Turning off the wrong-server is a thing that bit me before I installed molly-guard. These days that, and similar, is a tweak I apply to all hosts I control.
(molly-guard makes you type in the hostname before a halt/shutdown/reboot command.)
Steve Kemp? Slightly unrelated, but i just want to say i'm (still) a big fan of your old 2004 program window.exe. Very handy for unhiding the odd broken program.
Have a wonderful day! (and i'll definitely look at installing molly-guard on my production debian servers)
