1、打开bashrc
sudo vim ~/.bashrc
2、增加如下命令
function git_branch {
ref=$(git symbolic-ref HEAD 2> /dev/null) || return;
echo "("${ref#refs/heads/}")";
}
function parse_git_dirty {
local git_status=$(git status 2> /dev/null | tail -n1) || $(git status 2> /dev/null | head -n 2 | tail -n1);
if [[ "$git_status" != "" ]]; then
local git_now; # 标示
if [[ "$git_status" =~ nothing\ to\ commit || "$git_status" =~ Your\ branch\ is\ up\-to\-date\ with ]]; then
git_now="=";
elif [[ "$git_status" =~ Changes\ not\ staged || "$git_status" =~ no\ changes\ added ]]; then
git_now='~';
elif [[ "$git_status" =~ Changes\ to\ be\ committed ]]; then #Changes to be committed
git_now='*';
elif [[ "$git_status" =~ Untracked\ files ]]; then
git_now="+";
elif [[ "$git_status" =~ Your\ branch\ is\ ahead ]]; then
git_now="#";
fi
echo "${git_now}";
fi
}

3、生效命令
