1- If you don't have bash-completion ... : <code>sudo apt-get install bash-completion</code>

2- Edit your .bashrc file and check (or add) :

<pre><code>if [ -f /etc/bash_completion ]; then
 . /etc/bash_completion
fi
</code></pre>

3- ... before your prompt line : <code>export PS1='$(__git_ps1) \w\$ '</code> 
(__git_ps1 will show your git branch)

4- do <code>source .bashrc</code>

<h2>git 1.9.3 or later: use <code>__git_ps1</code></h2>

Git provides a shell script called <a href="https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh" rel="noreferrer"><code>git-prompt.sh</code></a>, which includes a function <code>__git_ps1</code> that

<blockquote>
 prints text to add to bash PS1 prompt (includes branch name)
</blockquote>

Its most basic usage is:

<pre><code>$ __git_ps1
(master)
</code></pre>

It also takes an optional format string:

<pre><code>$ __git_ps1 'git:[%s]'
git:[master]
</code></pre>

<h3>How to Get It</h3>

First, copy the file to somewhere (e.g. <code>~/.git-prompt.sh</code>).

Option 1: use an existing copy on your filesystem. Example (Mac OS X 10.15):

<pre><code>$ find / -name 'git-prompt.sh' -type f -print -quit 2&gt;/dev/null
/Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh
</code></pre>

Option 2: Pull the script <a href="https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh" rel="noreferrer">from GitHub</a>.

Next, add the following line to your <code>.bashrc/.zshrc</code>:

<pre><code>source ~/.git-prompt.sh
</code></pre>

Finally, change your <code>PS1</code> to call <code>__git_ps1</code> as command-substitution:

Bash: 

<pre><code>PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
</code></pre>

Zsh:

<pre><code>setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
</code></pre>

<h3>git &lt; 1.9.3</h3>

But note that only git 1.9.3 (May 2014) <a href="https://unix.stackexchange.com/questions/33617/how-can-i-update-to-a-newer-version-of-git-using-apt-get/170831#170831">or later</a> allows you to safely display that branch name(!)

See <a href="https://github.com/git/git/commit/8976500cbbb13270398d3b3e07a17b8cc7bff43f" rel="noreferrer">commit 8976500</a> by <a href="https://github.com/richardhansen" rel="noreferrer">Richard Hansen (<code>richardhansen</code>)</a>:

<blockquote>
 Both bash and zsh subject the value of PS1 to parameter expansion, command substitution, and arithmetic expansion. 
 
 Rather than include the raw, unescaped branch name in <code>PS1</code> when running in two- or
 three-argument mode, construct <code>PS1</code> to reference a variable that holds the branch name. 
 
 Because the shells do not recursively expand, this avoids arbitrary code execution by specially-crafted branch names such as 
</blockquote>

<pre><code>'$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)'.
</code></pre>

What devious mind would name a branch like that? ;) (<a href="http://xkcd.com/327/" rel="noreferrer">Beside a Mom as in xkcd</a>)

<h3>More Examples</h3>

<a href="https://stackoverflow.com/users/172274/still-dreaming-1">still_dreaming_1</a> reports <a href="https://stackoverflow.com/questions/15883416/adding-git-branch-on-the-bash-command-prompt/24716445?noredirect=1#comment54332815_24716445">in the comments</a>:

<blockquote>
 This seems to work great if you want a color prompt with <code>xterm</code> (in my <code>.bashrc</code>): 
</blockquote>

<pre><code>PS1='\[\e]0;\u@\h: \w\a\]\n${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\03‌​3[01;34m\]\w\[\033[00m\]$(__git_ps1)\$ ' 
</code></pre>

<blockquote>
 Everything is a different color, including the branch.
</blockquote>

In in Linux Mint 17.3 Cinnamon 64-bit: 

<pre><code>PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[00m\]$(__git_ps1) \$ '

I have tried a small script in python that goes in a bin folder....
'gitprompt' file

<pre><code>#!/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 "-"
</code></pre>

Make it executable and stuff

Then adjust the bash prompt accordingly like : 

<pre><code>\u:\w--[$(gitprompt)] \$ 
</code></pre>

Follow the steps as below: (Linux)

Edit the file <code>~/.bashrc</code>, to enter following lines at its end (In case, of Mac, file would be <code>~/.bash_profile</code>)

<pre><code># Git branch in prompt.
parse_git_branch() {
 git branch 2&gt; /dev/null | sed -e '/^[^*]/d' -e 's/* $.*$/ (\1)/'
}
export PS1="\u@\h \W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "
</code></pre>

Now, start the new terminal window, and try entering to any git-repo. The current branch would be shown, with the prompt.

If you use the <a href="https://github.com/fish-shell/fish-shell" rel="nofollow noreferrer">fish shell</a> its quite straight forward.
fish is an interactive shell which comes with lots of goodies. You can install it using <code>apt-get</code>.

<pre><code>sudo apt-get install fish
</code></pre>

you can then change the prompt setting using

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

now go to <code>http://localhost:8001/</code>
open the prompt tab and choose the classic + git option

Follow the below steps to show the name of the branch of your GIT repo in ubuntu terminal: 

step1: open terminal and edit .bashrc using the following command. 

vi .bashrc

step2: add the following line at the end of the .bashrc file :

<pre><code>parse_git_branch() {
git branch 2&gt; /dev/null | sed -e '/^[^*]/d' -e 's/* $.*$/ (\1)/' }
</code></pre>

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

step3: source .bashrc in the root (home) directory by doing:

/rootfolder:~$ <code>source .bashrc</code>

Step4: Restart and open the terminal and check the cmd. Navigate to your GIt repo directory path and you are done. :)

At first, open your Bash Profile in your home directory. The easiest way to open &amp; edit your bash_profile using your default editor.
For example, I open it using the VS Code using this command: code .bash_profile.
Then just paste the following codes to your Bash.
<pre><code>parse_git_branch() {
 git branch 2&gt; /dev/null | sed -e '/^[^*]/d' -e 's/* $.*$/ (\1)/'
}

export PS1=&quot;\u@\h \W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ &quot;
</code></pre>
The function
<blockquote>
parse_git_branch()
</blockquote>
will fetch the branch name &amp; then through PS1 you can show it in your terminal.
Here,
<blockquote>
\u = Username
@ = Static Text
\h = Computer Name
\w = Current Directory
$ = Static Text
</blockquote>
You can change or remove these variables for more customization.
<hr />
If you use Git for the first time in terminal or instantly after configuration, maybe sometimes you can not see the branch name.
If you get this problem, don't worry. In that case, just make a sample repository and commit it after some changes. When the commit command will execute once, the terminal will find git branch from then.

I wanted a clean solution that appended to the existing prompt instead of replacing it. As with other solutions, add this to the bottom of your .bashrc
<pre><code># function
parse_git_branch() {
 if [ -n &quot;$(git rev-parse --git-dir 2&gt; /dev/null)&quot; ]; then
 echo &quot;($(git rev-parse --abbrev-ref HEAD)) &quot;
 fi
}

# environment customization
export PS1=&quot;$PS1\$(parse_git_branch)&quot;
</code></pre>
A typical setup would yield a prompt that looks like
<code>user@machine:/path/to/git/project$ (branch-name)</code>

I tried adding the git branch I'm currently working on (checked-out) on the bash prompt without success.. (while keeping my current path which shows the active directory/file intact)
I have a .bashrc file on my home, but I also saw many people mentioning the .profile file..

我尝试在bash提示符下添加我当前正在处理的git分支(已签出)，但没有成功。(同时保持当前路径，其中显示活动目录/文件完好无损)我在家里有一个.bashrc文件，但我也看到很多人提到.profile文件。
