用git创建一个临时分支名称 [英] create a temporary branch name with git

问题描述

与这个问题稍有关系我想与一个临时分支合作在一个shell脚本中。

有点类似于：

  cd $（git rev-parse --show-toplevel）&& 
 git subtree split --prefix = some_subfolder -b temp&& 
 git push my_remote temp：publication_branch -f 
  

现在，我不确定这是什么如果分支 temp 已经存在，在任何情况下我都不希望 my_remote / publication_branch 的结果为取决于此。而且我也不想修改分支 temp （假设我对它有不相关的东西）。最后，我还会在最后做一个清理工作。

  cd $（git rev-parse --show-toplevel）& ;&安培; 
 git subtree split --prefix = some_subfolder -b temp&& 
 git push my_remote temp：publication_branch -f 
 git branch -D temp 
  

所以我在寻找的是一种创建临时分支名称的方法，它类似于 mktemp ？有没有可以创建一个临时分支名称的git命令？

解决方案

对于这个特定的任务，您可以使用split而不用<$ c

lockquote

成功拆分后，一个单独的提交ID被打印到标准输出。这对应于新创建的树的HEAD，无论您想要如何操作，您都可以操作该树。

所以

  split_head =`git subtree split --prefix = some_subfolder` 
 git push my_remote$ split_head：publication_branch -f 
  




Slightly related to this question I'd like to work with a temporary branch in a shell script.

somewhat along the lines of :

cd $(git rev-parse --show-toplevel) &&
git subtree split --prefix=some_subfolder -b temp &&
git push my_remote temp:publication_branch -f

Now, I'm not sure what this will do if the branch temp already exists, in any case I don't want the result on my_remote/publication_branch to depend on that. And I also don't want to modify the branch temp (assuming I have it for something unrelated). At best, I would also do a cleanup at the end

cd $(git rev-parse --show-toplevel) &&
git subtree split --prefix=some_subfolder -b temp &&
git push my_remote temp:publication_branch -f
git branch -D temp

So what I'm looking for is a way to create a temporary branch name that doesn't exist yet, similar to mktemp? Is there a git command which can create a temporary branch name?

解决方案

For this specific task you can use split without -b, by using this (from its manual):

After splitting successfully, a single commit id is printed to stdout. This corresponds to the HEAD of the newly created tree, which you can manipulate however you want.

So

split_head=`git subtree split --prefix=some_subfolder`
git push my_remote "$split_head":publication_branch -f
