I have a problem with terminal display configuration in macOS Big Sur 11.1
I want it to look like windows terminal from CMDer editor. Which can be used in the picture below
(img) I want to have something like this
I was very used to to this look of a terminal so I started to dig for solution.
I found, that I need to configure .zshrc file to change colour and add git information when needed.
I found the code which needs to be set in .zshrc file:
parse_git_branch() {
git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}
COLOR_DEF=$'\e[0m'
COLOR_USR=$'\e[38;5;44m'
COLOR_DIR=$'\e[38;5;106m'
COLOR_GIT=$'\e[38;5;208m'
NEWLINE=$'\n'
setopt PROMPT_SUBST
export PROMPT='${COLOR_USR}%n ${COLOR_DEF}in ${COLOR_DIR}%d ${COLOR_GIT}$(parse_git_branch)${COLOR_DEF}${NEWLINE}Ⲗ '
And it works when it comes to colours. I’m not able to make parse_git_branch function to work. I don't know what is going on here. In other post there is info that the method works.
(img) currently, I have something like this. With no git branching information
Here you go:
parse_git_branch() {
local branch=$(git rev-parse --abbrev-ref HEAD 2>/dev/null)
# If the branch is non-zero
if [[ -n $branch ]]; then
# -n: Don't print a newline at the end.
# -P: Substitute prompt expansions.
# %F{y}: Foreground color yellow
print -nP - "%F{y}($branch"
local tracking=$(git rev-parse --abbrev-ref --symbolic-full-name #{u} 2>/dev/null)
[[ -n $tracking ]] &&
print -nP - " -> $tracking"
print - ')'
fi
}
setopt promptsubst
# %F{g}: Foreground color green
# %~: pwd with named dir substitution
# %f: Default foreground color
export PS1='%F{g}%~ $(parse_git_branch)
%fⲖ '

Zsh manual: prompt expansion
I'm a Windows user with the Git Bash shell as my daily-driver. I'm curious how the __git_ps1 function updates the prompt every time you change a directory. It's really the only example of updating the bash prompt on the fly that I've seen. I want to leverage this behavior in my own function to add a display on my prompt if I have an RDP session open.
tldr: Any ideas on how the __git_ps1 function evaluates the bash prompt on the fly????
So here is my simple function to see if the RDP client is running
function __rdp_ps1() {
local MATCH=
if tasklist | grep --quiet mstsc; then
MATCH="\e[41mRDP\e[0m"
fi
echo "$MATCH"
}
So the idea is I want to display RDP with a red background, and I want my shell to evaluate this on the fly the same way __git__ps1 is seemingly able to.
What I've investigated (without real success) so far
/etc/profile.d/git-prompt.sh
This block seems to create the PS1 my shell is using
PS1='\[\033]0;$TITLEPREFIX:$PWD\007\]' # set window title
PS1="$PS1"'\n' # new line
PS1="$PS1"'\[\033[32m\]' # change to green
PS1="$PS1"'\u#\h ' # user#host<space>
PS1="$PS1"'\[\033[35m\]' # change to purple
PS1="$PS1"'$MSYSTEM ' # show MSYSTEM
PS1="$PS1"'\[\033[33m\]' # change to brownish yellow
PS1="$PS1"'\w' # current working directory
if test -z "$WINELOADERNOEXEC"
then
GIT_EXEC_PATH="$(git --exec-path 2>/dev/null)"
COMPLETION_PATH="${GIT_EXEC_PATH%/libexec/git-core}"
COMPLETION_PATH="${COMPLETION_PATH%/lib/git-core}"
COMPLETION_PATH="$COMPLETION_PATH/share/git/completion"
if test -f "$COMPLETION_PATH/git-prompt.sh"
then
. "$COMPLETION_PATH/git-completion.bash"
. "$COMPLETION_PATH/git-prompt.sh"
PS1="$PS1"'\[\033[36m\]' # change color to cyan
# tried hamjamming PS1="$PS1 `__rdp_ps1`" here, it only works on login
PS1="$PS1"'`__git_ps1`' # bash function
fi
fi
PS1="$PS1"'\[\033[0m\]' # change color
PS1="$PS1"'\n' # new line
PS1="$PS1"'$ ' # prompt: always $
So I went to see where this file was being sourced to see if that could lead to the answer
/etc/bash.bashrc
Last line held the gold
# Fixup git-bash in non login env
shopt -q login_shell || . /etc/profile.d/git-prompt.sh`
So I evaluated shopt login_shell and it's always on, but I don't really know what that means because the comment leads me to believe that when login env is off, the prompt script will be evaluated
Any ideas???
Your problem might be that you define your $PS1 with double quotes, which bash interprets when executing. Which means that __rdp_ps1 is ran when $PS1 is defined.
In your .bashrc, try replacing the definition with:
PS1='$PS1 `__rdp_ps1`' # Note the single quote.
I have a similar feature on my PS1 (but to display the number of jobs in the background), here is the full version (available here: https://github.com/padawin/dotfiles/blob/master/.bashrc#L70):
function j(){
jobs | wc -l | egrep -v ^0 | sed -r 's/^([0-9]+)/ (\1)/'
}
PROMPT_COMMAND=__prompt_command # Func to gen PS1 after CMDs
__prompt_command() {
local EXIT="$?" # This needs to be first
PS1="$(virtual_env_name)"
local RCol='\[\e[0m\]'
local Red='\e[0;31m'
local Gre='\e[0;32m'
local Blu='\e[1;34m'
PS1+="${Gre}\u#\h$(j)${RCol}: ${Red}\w${Blu}$(__git_ps1)"
if [ $EXIT != 0 ]; then
PS1+="$Red \342\234\226 (${EXIT})"
else
PS1+="$Gre \342\234\224"
fi
PS1+="$RCol\n> "
}
Which can be simplified as the following in .bashrc:
function j(){
jobs | wc -l | egrep -v ^0 | sed -r 's/^([0-9]+)/ (\1)/'
}
PS1='\u$(j) > ' # Note the single quote here
Which behaves as follow:
padawin > vim
[1]+ Stopped vim
padawin (1) > fg
vim
padawin >
Not directly a solution but this might help: if you want to know where the __git_ps1 function lives locally on your filesystem so you can experiment with making edits, you can do
grep -r __git_ps1 /
which searches for the string '__git_ps1' across the file contents of git bash's entire filesystem (where / is actually C:\Program Files\Git or wherever you have it installed).
For me, it was at /mingw64/share/git/completion/git-prompt.sh
My use case was removing the parenthesis from the branch name, which I did by changing this line:
local printf_format=' (%s)'
in the __git_ps1 () function
What you are looking for is PROMPT_COMMAND. Bash will execute whatever is in there before displaying a prompt. If your PS1 is being updated on-the-fly, you probably already have a PROMPT_COMMAND.
I'm getting this Annoying git_prompt: command not found error. I got a new Mac, and I'm trying to use my old .bash_profile into the new computer. I used Thoughtbot's laptop configuration which worked well last time.
I'm running on Mac Os Sierra, here is my .bash_profile:
# Configuring Our Prompt
# ======================
# if you install git via homebrew, or install the bash autocompletion via homebrew, you get __git_ps1 which you can use in the PS1

# enough to change it
# This function is called in your prompt to output your active git branch.

# The /usr directory is a convention from linux that creates a common place to put
# files and executables that the entire system needs access too. It tries to be user
# independent, so whichever user is logged in should have permissions to the /usr directory.
# We call that /usr/local. Within /usr/local, there is a bin directory for actually
# storing the binaries (programs) that our system would want.
# Also, Homebrew adopts this convetion so things installed via Homebrew
# get symlinked into /usr/local
export USR_PATHS="/usr/local:/usr/local/bin:/usr/local/sbin:/usr/bin"
# Hint: You can interpolate a variable into a string by using the $VARIABLE notation as below.
# We build our final PATH by combining the variables defined above
# along with any previous values in the PATH variable.
# Our PATH variable is special and very important. Whenever we type a command into our shell,
# it will try to find that command within a directory that is defined in our PATH.

I've been watching some of the Team Treehouse videos and they have a very nice looking terminal when working with Git.
For example they have (something similar):
mike#treehouseMac: [/Work/test - feature-branch-name] $ git add .
mike#treehouseMac: [/Work/test - feature-branch-name] $ git commit -m "Some feature."
mike#treehouseMac: [/Work/test - feature-branch-name] $ git checkout master
mike#treehouseMac: [/Work/test - master] $ git status
How can my terminal show me some useful information of what branch I'm on, with colors to distinguish bits of the data I want? Is there some sort of de-facto plugin I haven't found yet?
I'm using Mac OSX 10.8
For anyone looking for how to do this in macOS Catalina or above (10.15+ incl. Big Sur 11.0) which has deprecated bash in favour of zsh, here is my .zshrc file:
parse_git_branch() {
git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}
COLOR_DEF='%f'
COLOR_USR='%F{243}'
COLOR_DIR='%F{197}'
COLOR_GIT='%F{39}'
NEWLINE=$'\n'
setopt PROMPT_SUBST
export PROMPT='${COLOR_USR}%n#%M ${COLOR_DIR}%d ${COLOR_GIT}$(parse_git_branch)${COLOR_DEF}${NEWLINE}%% '
If you don't like the colours I have used, replace the 243/197/39 values with the colour codes as defined here:
https://misc.flogisoft.com/bash/tip_colors_and_formatting
Simple way
Open ~/.bash_profile in your favorite editor and add the following content to the bottom.
Git branch in prompt.
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u#\h \[\033[32m\]\w - \$(parse_git_branch)\[\033[00m\] $ "
Add Git Branch To Terminal Prompt (Mac)
It's not about a plugin. It's about prompt tricks in the shell.
For a cool setup in bash, check out the dotfiles project of this guy:
https://github.com/mathiasbynens/dotfiles
To get a fancy prompt, include the .bash_prompt in your ~/.bash_profile or ~/.bashrc.
To get the exact same prompt as in your question, change the export PS1 line at the end of .bash_prompt like this:
export PS1="\[${BOLD}${MAGENTA}\]\u\[$WHITE\]#\[$ORANGE\]\h\[$WHITE\]: [\[$GREEN\]\w\[$WHITE\]\$([[ -n \$(git branch 2> /dev/null) ]] && echo \" - \")\[$PURPLE\]\$(parse_git_branch)\[$WHITE\]] \$ \[$RESET\]"
I ended up using all the .bash* files from this repository about a month ago, and it's been really useful for me.
For Git, there are extra goodies in .gitconfig.
And since you're a mac user, there are even more goodies in .osx.
To expand on the existing great answers, a very simple way to get a great looking terminal is to use the open source Dotfiles project.
https://github.com/mathiasbynens/dotfiles
Installation is dead simple on OSX and Linux. Run the following command in Terminal.
git clone https://github.com/mathiasbynens/dotfiles.git && cd dotfiles && source bootstrap.sh
This is going to:
Git clone the repo.
cd into the folder.
Run the installation bash script.
For Mac Catilina 10.15.5 and later version:
add in your ~/.zshrc file
function parse_git_branch() {
git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}
setopt PROMPT_SUBST
export PROMPT='%F{grey}%n%f %F{cyan}%~%f %F{green}$(parse_git_branch)%f %F{normal}$%f '
My prompt includes:
Exit status of last command (if not 0)
Distinctive changes when root
rsync-style user#host:pathname for copy-paste goodness
Git branch, index, modified, untracked and upstream information
Pretty colours
Example:
To do this, add the following to your ~/.bashrc:
#
# Set the prompt #

export GIT_PS1_SHOWDIRTYSTATE=1 # '*'=unstaged, '+'=staged

In 2019, I think git branch --show-current is a better command than the accepted answer.
$ git branch --show-current
master
(Added in git 2.22 release in June 2019)
It runs much faster as it doesn't need to iterate through all branches. Similarly git branch should be avoided too in the command prompt as it slows down your prompt if you have many local branches.
Put it in a function to use anywhere on command prompt:
# This function returns '' in all below cases:
# - git not installed or command not found
# - not in a git repo
# - in a git repo but not on a branch (HEAD detached)
get_git_current_branch() {
git branch --show-current 2> /dev/null

Just Install the oh-my-zsh plugins as described in this link.
It works best on macOS and Linux.
Basic Installation
Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl or wget.
via curl
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
via wget
sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
for anyone still looking for this , i just installed ohmyz
https://ohmyz.sh/#install and the branches it's showing
In the new Catalina OS for Mac
i) zsh way. Add below lines in .zshrc
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ \1/'
}
COLOR_DEF='%f'
COLOR_DIR='%F{197}'
COLOR_GIT='%F{33}'
setopt PROMPT_SUBST
export PROMPT='${COLOR_DIR}%1d${COLOR_DEF}${COLOR_GIT}$(parse_git_branch)${COLOR_DEF} $ '
ii) Or to use old bash, you need to change
System Preference -> Users & Groups -> Right click user user
-> Advanced Option -> Login shell -> /bin/bash
Write .bash_profile as below and restart the system
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ \1/'
}
export PS1="\W\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "
Output: FolderName BranchName $
The git package installed on your system includes bash files to aid you in creating an informative prompt. To create colors, you will need to insert terminal escape sequences into your prompt. And, the final ingredient is to update your prompt after each command gets executed by using the built-in variable PROMPT_COMMAND.
Edit your ~/.bashrc to include the following, and you should get the prompt in your question, modulo some color differences.
#
# Git provides a bash file to create an informative prompt. This is its standard

# a built in Bash variable that gets evaluated before each render of the prompt.
#
export PROMPT_COMMAND="PS1=\"\${color_start}\${color_bg_blue}\${color_end}\u#\h [\w\$(__git_ps1 \" - %s\")]\${color_reset}\n\$ \""
#
# If you find that the working directory that appears in the prompt is ofter too long,
# then trim it.
#
export PROMPT_DIRTRIM=3
There are many PS1 generators but ezprompt has the git status (2nd tab 'Status Elements' ) also.
For macOS:
Step 1:
Create and edit a .zshrc file that will be used for terminal configuration.
touch ~/.zshrc; open ~/.zshrc
Step 2:
Add this to your ~/.zshrc file:
function parse_git_branch() {
git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}
setopt PROMPT_SUBST
export PROMPT='%F{grey}%n%f %F{cyan}%~%f %F{green}$(parse_git_branch)%f %F{normal}$%f '
Based on 6LYTH3's answer I've decided to post my own due to some improvements that may come in handy:
Simple solution
Open ~/.bash_profile and add the following content
# \[\e[0m\] resets the color to default color
reset_color='\[\e[0m\]'
# \[\033[33m\] sets the color to yellow
path_color='\[\033[33m\]'
# \e[0;32m\ sets the color to green
git_clean_color='\[\e[0;32m\]'
# \e[0;31m\ sets the color to red
git_dirty_color='\[\e[0;31m\]'
# determines if the git branch you are on is clean or dirty
git_prompt ()
{
# Is this a git directory?
if ! git rev-parse --git-dir > /dev/null 2>&1; then
return 0
fi
# Grab working branch name
git_branch=$(git branch 2>/dev/null| sed -n '/^\*/s/^\* //p')
# Clean or dirty branch
if git diff --quiet 2>/dev/null >&2; then
git_color="${git_clean_color}"
else
git_color="${git_dirty_color}"
fi
echo " [$git_color$git_branch${reset_color}]"
}
export PS1="${path_color}\w\[\e[0m\]$(git_prompt)\n"
This should:
1) Prompt the path you're in, in color: path_color.
2) Tell you which branch are you.
3) Color the name of the branch based on the status of the branch with git_clean_color
for a clean work directory and git_dirty_color for a dirty one.
4) The brackets should stay in the default color you established in your computer.
5) Puts the prompt in the next line for readability.
You can customize the colors with this list
Sophisticated Solution
Another option is to use Git Bash Prompt, install with this. I used the option via Homebrew on Mac OS X.
git_prompt_list_themes to see the themes but I didn't like any of them.
git_prompt_color_samples to see available colors.
git_prompt_make_custom_theme [<Name of base theme>] to create a new custom theme, this should create a .git-prompt-colors.sh file.
subl ~/.git-prompt-colors.sh to open git-prompt-colors.sh and customize:
The .git-prompt-colors.sh file should look like this with my customization
override_git_prompt_colors() {
GIT_PROMPT_THEME_NAME="Custom"
# Clean or dirty branch
if git diff --quiet 2>/dev/null >&2; then
GIT_PROMPT_BRANCH="${Green}"
else
GIT_PROMPT_BRANCH="${Red}"
fi
}
reload_git_prompt_colors "Custom"
Hope this helps, have a great day!
In Catalina and above, you can open your .zshrc file by running nano ~/.zshrc, and posting the following at the top of the document:
# Show git branch in terminal
function parse_git_branch() {
git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}
COLOR_DEF=$'\e[0m'
COLOR_USR=$'\e[38;5;243m'
COLOR_DIR=$'\e[38;5;220m’
COLOR_GIT=$'\e[38;5;39m'
setopt PROMPT_SUBST
export PROMPT='${COLOR_USR}%n ${COLOR_DIR}%~
${COLOR_GIT}$(parse_git_branch)${COLOR_DEF} $ '
Exit and save. Restart your terminal, or run exec zsh and that should be it.
OR
You can check out this theme and see if you like it. It is really easy to install and looks good in my opinion:
https://github.com/romkatv/powerlevel10k#configuration
Hope that helps.
From Mac OS Catalina
.bash_profile is replaced with .zprofile
Step 1:
Create a .zprofile
touch .zprofile
Step 2:
nano .zprofile
type below line in this
source ~/.bash_profile
and save(ctrl+o return ctrl+x)
Step 3:
Restart your terminal
To Add Git Branch Name
Now you can add below lines in .bash_profile
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u#\h \[\033[32m\]\w - \$(parse_git_branch)\[\033[00m\] $ "
Restart your terminal this will work.
Note:
Even you can rename .bash_profile to .zprofile that also works.
Keep it fast, keep it simple
put this in your ~/.bashrc file.
git_stuff() {
git_branch=$(git branch --show-current 2> /dev/null)
if [[ $git_branch == "" ]];then
echo -e ""
elif [[ $git_branch == *"Nocommit"* ]];then
echo -e "No commits"
else
echo -e "$git_branch"
fi
}
prompt() {
PS1="\e[2m$(date +%H:%M:%S.%3N) \e[4m$(git_stuff)\033[0m\n\w$ "
}
PROMPT_COMMAND=prompt
Then source ~/.bashrc
Did some searching & then adjusted it a bit & settled with this.
vi ~/.zshrc
And within zshrc file ->
function git_branch_name()
{
branch=$(git symbolic-ref HEAD 2> /dev/null | awk 'BEGIN{FS="/"} {print $NF}')
if [[ $branch == "" ]];
then
:
else
echo '- ('$branch')'
fi
}
setopt prompt_subst
prompt='%n %1/ $(git_branch_name) $ '
I've got the following variable set in my cygwin $HOME/.bashrc
PATH=/bin:/usr/sbin:"/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin":$PATH
Problem is that when I login and the .bashrc gets executed, I get starting duplicates as follows:
Dragos#dragos ~
$ echo $PATH | tr ':' '\n'

I don't modify $PATH in my $HOME/.bashrc anywhere other than the set PATH= command above.
If I prepend only one path to $PATH, that would get duplicated as well:
PATH="/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin":$PATH
Results in:
Dragos#dragos ~
$ echo $PATH | tr ':' '\n'

So... Why the duplicates?
Addendum:
I found that I'm executing bash twice in my C:\cygwin\Cygwin.bat
The reason is that I have a context menu command to "Open Bash Here" that passes
a starting path to C:\cygwin\Cygwin.bat
Here's my C:\cygwin\Cygwin.bat
#echo off
C:
set PATH=%PATH%;C:\cygwin\bin
REM SHELL needed for any screen instances started from bash
set SHELL=/bin/bash
set HOME=C:\cygwin\home\Dragos

set HOMEPATH=\cygwin\home\Dragos
REM
if not [%1]==[] (
C:\cygwin\bin\cygpath %1 > tmpFile
set /p startingpath= < tmpFile
del tmpFile
)
if "%startingpath%"=="" start C:\cygwin\bin\mintty.exe --icon /Cygwin-Terminal.ico --size 140,50 --exec /bin/bash --login -c "exec /bin/bash -rcfile ~/.bashrc"

exit
Addendum:
Figured out that I need to pass --noprofile --norc to bash when calling bash.
Here's the updated C:\cygwin\Cygwin.bat
#echo off

exit
I don't have Cygwin installed, and I don't have a Windows machine, so I can't give you a boatload of details.
See if the man bash page can help you. In normal BASH, the /etc/profile, /etc/bashrc, the $HOME/.bash_profile, the $HOME/.bashrc, and sometimes the $HOME/.profile are all read in depending whether this is a login shell or not. Cygwin has it's own special versions of each of these files in the /etc directory. However, there's also other scripts that get invoked and can affect your Cygwin environment. For example, there are special scripts to import Windows environment variables including %PATH%.
In Cygwin, the default is to include the Windows %PATH% variable as part of the Cygwin path. It's actually a general import of all Windows environment variables (and depending upon the installation, the \ is sometimes converted to a / and short directory names are used).
If you open xterm windows and not standard Windows console windows for your Cygwin command line, you'll also have to check the xserve script (or whatever it's called) because that also imports a lot of stuff into the Cygwin environment.
I've used Cygwin in the past, and every time I use Cygwin, I find myself chasing down these exact things, plus a few other issues: For example, the default Kornshell load environment script has a bug in it. I believe they have a literal "^G" instead of a Ctrl-G, or maybe it was another control character. I can't remember. All I know is I spend about an hour or two cleaning up my Cygwin environment every time I install it. I like Cygwin, but it can be a pain.
Sorry I can't give you more specific directions.
Just set the PATH to whatever you like (without a reference to $PATH). You shouldn't trust the PATH that some random sysadmin thinks is a good PATH anyway. Do this in the file sourced last for your shell.
