在~/.bashrc文件中加入如下内容:
alias ll="ls -lh "
alias gs="git status "
alias gc="git checkout "
alias gb="git branch "
alias gm="git merge "
parse_git_branch() {
git branch 2> /dev/null | sed -e ‘/^[^*]/d‘ -e ‘s/* \(.*\)/ (\1)/‘
}
export PS1="\u@\w\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "
然后执行：source ~/.bashrc即可.
Mac可以修改/etc/bashrc，否则每次重启终端都要source ~/.bashrc
