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)] \$ 

这里是一个简单的干净的版本，我使用:link

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
txtylw='\e[0;33m' # Yellow
txtblu='\e[0;34m' # Blue
txtpur='\e[0;35m' # Purple
txtcyn='\e[0;36m' # Cyan
txtwht='\e[0;37m' # White
bldblk='\e[1;30m' # Black - Bold
bldred='\e[1;31m' # Red
bldgrn='\e[1;32m' # Green
bldylw='\e[1;33m' # Yellow
bldblu='\e[1;34m' # Blue
bldpur='\e[1;35m' # Purple

undblu='\e[4;34m' # Blue
undpur='\e[4;35m' # Purple
undcyn='\e[4;36m' # Cyan
undwht='\e[4;37m' # White
bakblk='\e[40m'   # Black - Background
bakred='\e[41m'   # Red
badgrn='\e[42m'   # Green
bakylw='\e[43m'   # Yellow
bakblu='\e[44m'   # Blue
bakpur='\e[45m'   # Purple
bakcyn='\e[46m'   # Cyan
bakwht='\e[47m'   # White
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"

如果你想了解更多，你可以在这里获得所有的dotfiles: https://github.com/jamming/dotfiles

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\$ '

1-如果你没有bash-completion…: sudo apt-get install bash-completion

2-编辑你的.bashrc文件并检查(或添加):

if [ -f /etc/bash_completion ]; then
  . /etc/bash_completion
fi

3 -…export PS1='$(__git_ps1) \w\$ ' (__git_ps1将显示你的git分支)

4- do source .bashrc

编辑:

进一步阅读:不要重新发明轮子

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
