I like to use colors in the shell to help me identify which machine I’m on. I also like to keep my dotfiles under git so it helps to have a simple way to programatically set which color I should be using on which machine.
1 2 3 4 5 6 7 if [ "$SSH_CONNECTION" == "" ]; then # Yellow prompt for local login PS1="[\[\033[01;33m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\]]$ " else # Red prompt for remote login PS1="[\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\]]$ " fi
By checking the existance of the
$SSH_CONNECTION variable it is easy to set one
color for my local machine and a different color for remote machines.
I’ve also found it useful to know roughly when a command was started and ended. By prepending the timestamp to my prompt it is easy
\t adds the timestamp
