混帐：快速命令去工作树的根 [英] git: a quick command to go to root of the working tree

问题描述

我想一个简单的Git命令去到仓库的根。

I wanted a simple git command to go up to the "root" of the repository.

我开始用一个脚本，但想通，我不能改变外壳活动目录，我不得不做一个函数。不幸的是，我不能直接与非划线的形式混帐根称呼它，比如

I started with a script, but figured that I cannot change active directory of the shell, I had to do a function. Unfortunately, I cannot call it directly with the non-dash form "git root", for instance.

function git-root() {
 if [ -d .git ]; then
  return 0
 fi

 A=..
 while ! [ -d $A/.git ]; do 
  A="$A/.."
 done
 cd $A
}

你有更好的解决办法？ （该功能已经飞快地写着，建议，欢迎）

Do you have a better solution? (the function has been written quickly, suggestions are welcome)

推荐答案

这已经被问过，<一个href=\"http://stackoverflow.com/questions/957928/is-there-a-way-to-get-to-the-git-root-directory-in-one-command\">Is有没有办法让git的根目录中的一个命令？复制@ docgnome的回答，他写道：

This has been asked before, Is there a way to get the git root directory in one command? Copying @docgnome's answer, he writes

cd $(git rev-parse --show-cdup)

请一个别名，如果你喜欢：

Make an alias if you like:

alias git-root='cd $(git rev-parse --show-cdup)'
