Answer 1

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

To reflect latest changes run following command

source ~/.bashrc

Output:-

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

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 :

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

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

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

/rootfolder:~$ source .bashrc

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

Here is how I configured the prompt to display Git status:

Get git-prompt script:

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

And customize your prompt adding the following code in your .bashrc file:

# 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
bldcyn='\e[1;36m' # Cyan
bldwht='\e[1;37m' # White
unkblk='\e[4;30m' # Black - Underline
undred='\e[4;31m' # Red
undgrn='\e[4;32m' # Green
undylw='\e[4;33m' # Yellow
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"

At first, open your Bash Profile in your home directory. The easiest way to open & 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.

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

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

The function

parse_git_branch()

will fetch the branch name & then through PS1 you can show it in your terminal.

Here,

\u = Username

@ = Static Text

\h = Computer Name

\w = Current Directory

$ = Static Text

You can change or remove these variables for more customization.

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.

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\$ '

Answer 6

root:~/project#  -> root:~/project(dev)# 

add the following code to the end of your ~/.bashrc

force_color_prompt=yes
color_prompt=yes
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
unset color_prompt force_color_prompt
