.bashrc and PS1 Environment
The combination of this .bashrc file and the PS1 variable makes my very useful PS1 prompt.
This config below will:
  • Make a very useful looking PS1 showing all adaptor IP addresses
  • PS1 will show date and time of command
  • Every command executed in bash will be logged to ~/.logs/.terminal_log/
