В ~/.bashrc добавляем такое:

parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
export PS1="\u@\h \[\e[32m\]\w \[\e[91m\]\$(parse_git_branch)\[\e[00m\]$ "

Или одной строкой:

grep parse_git_branch ~/.bashrc || cat >> ~/.bashrc <<EOF

parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
export PS1="\u@\h \[\e[32m\]\w \[\e[91m\]\\\$(parse_git_branch)\[\e[00m\]$ "
EOF
