nicer-bash-prompt
Create a nicer bash prompt including red prompt on production hosts, current git branch, and the last two directories in $PWD, like this:
It's completely driven by hostname so as long as you have a suitable pattern to production hostnames (e.g. xyprod01, 02, etc) it will work well, and you can use the same .bashrc in all environments.
Includes optional feature to sync your bash history across all terminal windows. This is nice but not everyone wants it, so it's disabled by default.
Installation
Include this in your .bashrc - it's not a complete bashrc, so just append it to the end of the .bashrc file.
Be sure to first comment out any previous PS1 settings - get this working first, then you can customize to fit.
Look for the CUSTOMIZE comments to configure for your hostnames, domain name, and so on.
Testing
Most of the code works on non-production hosts.
To show the red prompt on any host, use export SIMULATE_PROD=yes.
Use unset SIMULATE_PROD to clear this.
