我尝试了一个python小脚本，放在....文件夹中 “gitprompt”文件

#!/usr/bin/env python
import subprocess, os
s = os.path.join(os.getcwd(), '.git')
def cut(cmd):
    ret=''
    half=0
    record = False
    for c in cmd:
        if c == "\n":
            if not (record):
                pass
            else:
                break
        if (record) and c!="\n":
            ret = ret + c
        if c=='*':
            half=0.5
        if c==' ':
            if half == 0.5:
                half = 1
        if half == 1:
            record = True
    return ret
if (os.path.isdir(s)):
    out = subprocess.check_output("git branch",shell=True)
    print cut(out)
else:
    print "-"

让它可执行之类的

然后相应地调整bash提示符，如下:

\u:\w--[$(gitprompt)] \$ 

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]$(parse_git_branch)\n\$ '

vim ~/.bash

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)\[\033[00m\] $"

要反映最新的更改，请运行以下命令

source ~/.bashrc

输出:

chandrakant@NDL41104 ~/Chandrakant/CodeBase/LaravelApp (development) $

对于mac来说，这个很好用:http://martinfitzpatrick.name/article/add-git-branch-name-to-terminal-prompt-mac/:

# Git branch in prompt.
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

export PS1="\u@\h \W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "

如果你用的是鱼壳，那就很直接了。 Fish是一个互动的贝壳，里面有很多好吃的东西。您可以使用apt-get安装它。

sudo apt-get install fish

然后，您可以使用

> fish_config 
Web config started at 'http://localhost:8001/'. Hit enter to stop.
Created new window in existing browser session.

现在登录http://localhost:8001/ 打开提示选项卡并选择经典的+ git选项

现在点击使用提示按钮，你就设置好了。

下面是我如何配置提示符来显示Git状态:

获取git-prompt脚本:

curl -o ~/.git-prompt.sh https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

并自定义提示符，在.bashrc文件中添加以下代码:

# Load Git functions
source ~/.git-prompt.sh

# Syntactic sugar for ANSI escape sequences
txtblk='\e[0;30m' # Black - Regular
txtred='\e[0;31m' # Red
txtgrn='\e[0;32m' # Green

txtrst='\e[0m'    # Text Reset

# Prompt variables
PROMPT_BEFORE="$txtcyn\u@\h $txtwht\w$txtrst"
PROMPT_AFTER="\\n\\\$ "

# Prompt command
PROMPT_COMMAND='__git_ps1 "$PROMPT_BEFORE" "$PROMPT_AFTER"'

# Git prompt features (read ~/.git-prompt.sh for reference)
export GIT_PS1_SHOWDIRTYSTATE="true"
export GIT_PS1_SHOWSTASHSTATE="true"
export GIT_PS1_SHOWUNTRACKEDFILES="true"
export GIT_PS1_SHOWUPSTREAM="auto"
export GIT_PS1_SHOWCOLORHINTS="true"
