Answer 1

Try this:

Paste in ~/.profile or in ~/.bash_profile :

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


#update your prompt string
export PS1="[\u@\h \W]\\$\\$(git_branch)"

then source ~/.profile or source ~/.bash_profile

I'm on Windows and wanted to use git within MSYS2, not as a separate git bash terminal (which is what your friends seems to have). I downloaded Git for Windows and copied the following code from C:\\Program Files\\Git\\etc\\profile.d\\git-prompt.sh into my bashrc file:

    if test -f ~/.config/git/git-prompt.sh
then
    . ~/.config/git/git-prompt.sh
else
    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
            PS1="$PS1"'`__git_ps1`'   # bash function
        fi
    fi
    PS1="$PS1"'\[\033[0m\]'        # change color
    PS1="$PS1"'\n'                 # new line
    PS1="$PS1"'$ '                 # prompt: always $
fi

MSYS2_PS1="$PS1"               # for detection by MSYS2 SDK's bash.basrc

# Evaluate all user-specific Bash completion scripts (if any)
if test -z "$WINELOADERNOEXEC"
then
    for c in "$HOME"/bash_completion.d/*.bash
    do
        # Handle absence of any scripts (or the folder) gracefully
        test ! -f "$c" ||
        . "$c"
    done
fi

To do this, open an instance of MSYS2, open bashrc using any editor, for example with nano type nano ~/.bashrc , scroll to the bottom of the file, and paste the above code in. New MSYS2 instances should look like your friend's!

This is what my prompt looks like:

Instead of showing the full path, it just shows the current branch and directory. It's designed with the file git-prompt.sh which contains:

PS1='\[\033]0;$TITLEPREFIX:\W\007\]' # set window title
PS1="$PS1"'\n'                       # new line
PS1="$PS1"'\[\033[35m\]'             # change to purple
PS1="$PS1"'git'                      # git user
if test -z "$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
        PS1="$PS1"'`__git_ps1` '   # bash function
    fi
fi
PS1="$PS1"'\[\033[33m\]'       # change to brownish yellow
PS1="$PS1"'@\W'                # current working directory
PS1="$PS1"'\n'                 # new line
PS1="$PS1"'\[\033[32m\]'       # change to green
PS1="$PS1"'> '                 # prompt: default $
PS1="$PS1"'\[\033[0m\]'        # change color

To edit the git-prompt.sh file, first go to your user profile folder. Example:

C:\Users\myProfile

Then go to the folder \.config\git Example:

C:\Users\myProfile\.config\git

Then create or edit the git-prompt.sh file, and paste in the code block above. The full path of git-prompt.sh should be:

C:\Users\myProfile\.config\git\git-prompt.sh

For reference, the default git-prompt.sh file is below:

if test -f /etc/profile.d/git-sdk.sh
then
    TITLEPREFIX=SDK-${MSYSTEM#MINGW}
else
    TITLEPREFIX=$MSYSTEM
fi

if test -f ~/.config/git/git-prompt.sh
then
    . ~/.config/git/git-prompt.sh
else
    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
            PS1="$PS1"'`__git_ps1`'   # bash function
        fi
    fi
    PS1="$PS1"'\[\033[0m\]'        # change color
    PS1="$PS1"'\n'                 # new line
    PS1="$PS1"'$ '                 # prompt: always $
fi

MSYS2_PS1="$PS1"     # for detection by MSYS2 SDK's bash.basrc

# Evaluate all user-specific Bash completion scripts (if any)
if test -z "$WINELOADERNOEXEC"
then
    for c in "$HOME"/bash_completion.d/*.bash
    do
        # Handle absence of any scripts (or the folder) gracefully
        test ! -f "$c" ||
        . "$c"
    done
fi

The default git-prompt.sh file may be found in any of the following folders:

C:\Users\myProfile\AppData\Local\Programs\Git\etc\profile.d\git-prompt.sh

C:\Program Files\Git\etc\profile.d\git-prompt.sh

Those can be edited directly instead of making a copy in your user profile. Editing those may change the prompt for all user profiles in your computer.

Git bash 与任何其他 bash 一样，因此只需运行pwd （当前工作目录），对于分支使用git branch -a
