自定义编辑器头
编辑./bash_profile或者/.profile文件，重新打开termial就可以看到变化
比如：
export PS1="\u🔥\w\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h\033[32m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] ☀️✨💫🚗🚗$ "
