Thank you for this, I have just updated my bashrc from this:

git_branch () {
    # Get current Git branch
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
    }

git_last_update () {
    # Get last update on current Git branch
    git log 2> /dev/null | head -n 3 | grep ^Date | cut -f4- -d' ';
    }

export PS1="\[\033[0;32m\]\[\033[0m\033[0;38m\]\u\[\033[0;36m\]@\[\033[0;36m\]\h:\w\[\033[0;32m\] \$(git_branch) \$(git_last_update)\n\[\033[0;32m\]└─\[\033[0m\033[0;31m\] [\D{%F %T}] \$\[\033[0m\033[0;32m\] >>>\[\033[0m\] "

to this:

_ip_add=$(ip addr | grep -w inet | gawk '{if (NR==2) {$0=$2; gsub(/\//," "); print $1;}}')
__git_status() {
    STATUS=$(git status 2>/dev/null |
    awk '
    /^On branch / {printf($3)}
    /^Changes not staged / {printf("|?Changes unstaged!")}
    /^Changes to be committed/ {printf("|*Uncommitted changes!")}
    /^Your branch is ahead of/ {printf("|^Push changes!")}
    ')
    if [ -n "$STATUS" ]; then
        echo -ne " ($STATUS) [$(git log 2> /dev/null | head -n 3 | grep ^Date | cut -f4- -d' ')]"
    fi
}
__ps1_startline="\[\033[0;32m\]\[\033[0m\033[0;38m\]\u\[\033[0;36m\]@\[\033[0;36m\]\h on ${_ip_add}:\w\[\033[0;32m\]"
__ps1_endline="\[\033[0;32m\]└─\[\033[0m\033[0;31m\] [\D{%F %T}] \$\[\033[0m\033[0;32m\] >>>\[\033[0m\] "
export PS1="${__ps1_startline} \$(__git_status)\n ${__ps1_endline}"
