使用 Git,两个常规(非裸)存储库无法直接来回推送/拉取文件。必须有一个中间裸存储库。显然,这有点像一对有孩子的已婚夫妇,而这对夫妇正在离婚。父母不会互相交谈,但他们会通过孩子交流。
所以,你有一个存储库,你将这个存储库克隆到一个裸存储库,然后将它克隆到第三个。第一个和第三个可以通过第二个存储库(裸存储库)交换信息。我想这是有道理的,因为您不希望有人能够在未经您同意的情况下将内容签入您的存储库,因为这可能会导致合并冲突等。
所以,这里有一个例子:
在 PC 上,在 ~/workspace 中
git init
echo "line 1" > afile.txt
git add .
git commit -m ‘initial import’
git clone --bare . ../remote-repository.git
git remote add origin ../remote-repository.git
git push --set-upstream origin master
在笔记本电脑上,在 ~/workspace 中(不要执行 git init 等)
git clone //LJZ-DELLPC/remote-repository.git/ .
// 然后进行各种提交,并推送它们:
echo "line 2" > afile.txt
git add afile.txt
git commit -m 'added line 2'
git push
然后回到 PC 上,在 ~/workspace
git pull
// 然后进行各种提交,并推送它们:
git push
在笔记本电脑上 git pull
等等..
这是一台机器上的一个绝对具体的例子,直接从命令窗口复制,这样我们就知道没有遗漏任何步骤,它确实有效,等等:
