1 Change \w to \W in ${HOME}/.bashrc
Ubuntu and Debian have long prompt string by default which includes full path of current directory.
username@hostname:/var/lib/git$
Change full path of current directory to current directory with changing \w to \W in ${HOME}/.bashrc.
$ sed -i -e 's/\\w/\\W/g' ~/.bashrc $ . ~/.bashrc

username@hostname:git$
After this change, bash prompt string is shortened by default.
