PS1 line with Git current branch and colors
提问by cfischer
Here is my current PS1:
这是我目前的 PS1：
export PS1='[\u@\h \W$(__git_ps1 " (%s)")]$ '
How can I display the current branch in a different color?
如何以不同的颜色显示当前分支？
采纳答案by Simon Whitaker
You can wrap the part that you want in colour with the following:
您可以使用以下方法包裹所需的颜色部分：
\e[0;32m- sets colour (in this case, to green)
\e[0;32m- 设置颜色（在本例中为绿色）
\e[m- sets colour back to the default
\e[m- 将颜色设置回默认值
For example, this sets the prompt to the last token of the current path, in green, followed by $in the default colour:
例如，这将提示设置为当前路径的最后一个标记，绿色，然后$是默认颜色：
export PS1='\e[0;32m\w\e[m $'
Other colours are available too. Have a look at this articleunder colorization for a comprehensive list of alternatives.
其他颜色也可用。在着色下查看这篇文章，以获取完整的替代方案列表。

Here is, part by part (and no Ruby):
这是部分（并且没有 Ruby）：
function color_my_prompt {
local __user_and_host="\[3[01;32m\]\u@\h"
local __cur_location="\[3[01;34m\]\w"
local __git_branch_color="\[3[31m\]"
#local __git_branch="\`ruby -e \"print (%x{git branch 2> /dev/null}.grep(/^\*/).first || '').gsub(/^\* (.+)$/, '() ')\"\`"
local __git_branch='`git branch 2> /dev/null | grep -e ^* | sed -E s/^\\\*\ \(.+\)$/\(\\\)\ /`'
local __prompt_tail="\[3[35m\]$"
local __last_color="\[3[00m\]"
export PS1="$__user_and_host $__cur_location $__git_branch_color$__git_branch$__prompt_tail$__last_color "
}
color_my_prompt
Looks like this (with my own terminal palette):
看起来像这样（使用我自己的终端调色板）：

It looks great on a Mac with the Novel theme. Sorry, but my indentation got munged a bit. Hack it till you like it.
它在具有小说主题的 Mac 上看起来很棒。对不起，但我的缩进有点变味了。破解它，直到你喜欢它。

If you are checked out at a branch, you get the branch name.
如果您在分行结账，您会得到分行名称。
If you are in a just init'd Git project, you just get '@'.
如果你在一个刚刚初始化的 Git 项目中，你只会得到“@”。
If you are headless, you get a nice human name relative to some branch or tag, with an '@' preceding the name.
如果你是无头的，你会得到一个相对于某个分支或标签的好听的人名，名字前面有一个“@”。
If you are headless and not an ancestor of some branch or tag you just get the short SHA1.
如果您是无头的并且不是某个分支或标签的祖先，您只会得到简短的 SHA1。
In addition, a red '-' signifies a clean work directory and index, and a red '+' signifies the opposite.
此外，红色的“-”表示干净的工作目录和索引，红色的“+”表示相反。

My uber-powerful multi-line Linux prompt!
我的超级强大的多行 Linux 提示符！
Put it either in your .bashrc or better: save it in /etc/bash-prompt and source it from your .bashrc.
Using tput is supposed to be the right way to do colors.
将它放在您的 .bashrc 或更好的文件中：将其保存在 /etc/bash-prompt 中并从您的 .bashrc 中获取它。
使用 tput 应该是处理颜色的正确方法。

local last_cmd=$?

local txtbold='$(tput bold)'
local txtblack='$(tput setaf 0)'

local txtyellow='$(tput setaf 3)'

For my Mac with the Homebrew theme, this works really well. Fully debugged and very fast, and completely self-contained. BONUS: Smart enough to ONLY show a git branch as part of the prompt when you're actually ina git repo! :)
对于我的带有 Homebrew 主题的 Mac，这非常有效。完全调试并且非常快速，并且完全独立。奖励：足够聪明，当您实际上在git 存储库中时，仅将 git 分支显示为提示的一部分！:)
# Color prompt for git
reset=$(tput sgr0)
boldgreen=$(tput setaf 2)$(tput bold)
cyan=$(tput sgr0)$(tput setaf 6)
boldred=$(tput setaf 1)$(tput bold)
boldwhite=$(tput setaf 7)$(tput bold)
boldyellow=$(tput setaf 3)$(tput bold)
PARENCLR=$'# So I know where I am in repos:
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ ()/'
}

Here's what it looks like: Mac + Homebrew + Color Git Prompt
这是它的样子： Mac + Homebrew + Color Git Prompt
If you want to have the full path (or remove the .../), then just change the -W to -w (and remove the .../).
如果您想拥有完整路径（或删除 .../），则只需将 -W 更改为 -w（并删除 .../）。

Modified version of @cmcginty's prompt that adds in the gitparsing function and uses slightly different spacing:
@cmcginty's prompt 的修改版本，增加了git解析函数并使用了稍微不同的间距：
This also uses \$in the prompt instead of $, which means you will get #when you are root.
这也在\$提示中使用而不是$，这意味着您将#在 root 时获得。

Just invoke tputwith the appropriate parameters. See the tput(1)and terminfo(5)man pages.
只需tput使用适当的参数调用即可。见tput(1)和terminfo(5)手册页。
