在终端中显示 git 用户名的 Bash 脚本

Question

Does anyone know how to show git username in the terminal?

I am using the following bash script for the branch, but, since I have several accounts I would like to show as well username or user email

BTW, I know I can use git config --global --list . The idea is to see the info in the terminal without having to check every time, as with the branch

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

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

Answer 1

You can use git config --get to get a single configuration value, like the username. Then, you can wrap it in a function:

parse_git_user() {
    git config --get user.email
}

And then you can incorporate it into the prompt ( PS1 ) in any format you wish. Eg:

export PS1="\u@\h \W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] ($(parse_git_user))$ "
# Here -----------------------------------------------------------^

I suspect you want to make sure you get the correct user.email for each of your projects? @Mureinik eloquently answered the question, but I think this may help you or someone else searching.

Rather than have the user.name in your prompt, I suggest you set it based on the remote url. That way it should just work™. It works by using a zsh hook every time you change into a directory.

autoload -Uz add-zsh-hook
set-git-email() {
  if [ -d .git ]; then
    remote=`git remote -v | awk '/\(push\)$/ {print $2}'`
    if [[ $remote == git@git.server.com:* ]]; then
       git config user.email user@email.com
    fi   
  fi
}
add-zsh-hook chpwd set-git-email
set-git-email
