Posts here will mostly contain full configuration files for my own reference and will not likely not have much explanation. See posts in the Guides category for more explanational posts.

I have a few customizations to the bash prompt and how bash interfaces with a terminal window.

Custom Bash Prompts

Default user prompt. Short and simple.

PS1='[\u@\h \w]$ '

The root prompt is the same as the user prompt, except red as a warning.

PS1='[\[\e[01;31m\]\u@\h \w\[\e[0m\]]$ '

Yellow prompt that I use on “jumper” boxes. They are normally SSH servers that sit between two networks.

PS1='[\[\e[01;33m\]\u@\h \w\[\e[0m\]]$ '

Update Terminal Title

This is taken from the CentOS default config in /etc/bashrc. I noticed that my terminal titles were updating on CentOS boxes, but not on Ubuntu boxes. This is the config to add to make things consistent.

case $TERM in
        PROMPT_COMMAND='printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"'
        PROMPT_COMMAND='printf "\033]0;%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"'
