bash 命令列上顯示git branch

之前網路上看到的方法,來源忘記了

function git_branch {
    ref=$(git symbolic-ref HEAD 2> /dev/null) || return;
    echo "("${ref#refs/heads/}") ";
}

function git_since_last_commit {
    now=`date +%s`;
    last_commit=$(git log --pretty=format:%at -1 2> /dev/null) || return;
    seconds_since_last_commit=$((now-last_commit));
    minutes_since_last_commit=$((seconds_since_last_commit/60));
    hours_since_last_commit=$((minutes_since_last_commit/60));
    minutes_since_last_commit=$((minutes_since_last_commit%60));
    
    echo "${hours_since_last_commit}h${minutes_since_last_commit}m ";
}

PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \[\033[0m\]\[\033[1;36m\]\$(git_branch)\[\033[01;34m\]\$ \[\033[00m\]"

#"\[\033[0;33m\]\$(git_since_last_commit)"

把他放到~/.bashrc即可
