Show git branch in your terminal shell prompt

[xhlwill]

vim ~/.bashrc
or vim ~/.bash_profile (Mac OS) and add these:

function find_git_branch {   
    local dir=. head  
    until [ "$dir" -ef / ]; do  
        if [ -f "$dir/.git/HEAD" ]; then  
            head=$(< "$dir/.git/HEAD")  
            if [[ $head == ref:\ refs/heads/* ]]; then  
                git_branch=" ${head#*/*/}"  
            elif [[ $head != '' ]]; then  
                git_branch=' (detached)'  
            else
                git_branch=' (unknown)'
            fi
            return
        fi
        dir="../$dir"
    done
    git_branch=''
}

PROMPT_COMMAND="find_git_branch; $PROMPT_COMMAND"

green=$'\e[1;32m'
magenta=$'\e[1;35m'
normal_colours=$'\e[m'

PS1="\[$green\]\u@\h:\w\[$magenta\]\$git_branch\[$green\]\\$\[$normal_colours\] "

Share and enjoy!

恩，按照这个弄了一下就好了。

官方提供了shell，功能更强大，能显示detached分支状态等，做个笔记
