了解何时使用git commit -m和git commit -am [英] Understanding when to use git commit -m and git commit -am

问题描述

我的主要问题是iti是否有意义，只要始终执行 git commit -am 而不是 git add 。其次是 git commit -m ？

我知道，-am表示它将添加所有修改TRACKED文件。因此，在我没有添加任何新文件的情况下，只需运行git commit -am而不是git add就可以了，但是这会被认为是最佳做法：

git add 。

  git commit -am消息
  

无论如何？

甚至相反：

  git add -A 
 
 git commit -ammessage
  

解决方案

：

git add。

git commit -am消息

无论如何？

不，没有这种最佳做法。只要你不想包含任何未跟踪的文件， git add + git commit -m 和 git commit -am 将完全相同。

有两种情况需要使用 git add ：

• 如果您想包含未跟踪的文件，并且
  
• 如果您不想提交所有已更改的内容

第二点尤其是许多人建议不要总是使用 commit -a ：
在编写代码一段时间后，您的工作副本中经常会有几种不同类型的更改（您正在处理的错误修复，无关的重命名，调试的一些临时更改...）。 commit -a 将风险放在一个提交中太多 - 在这些情况下，选择使用 git add 会更好。 git commit -a 。 p>

My main question here is whether iti makes sense to just always do git commit -am instead of git add . followed by git commit -m?

I understand that -am indicates that it will add all changes from modified TRACKED files. So in a situation where I did not add any new files, it would make sense to just run git commit -am instead of git add, but would it be considered best practice to just do:

git add .

git commit -am "message"

anyway?

or even instead:

git add -A

git commit -am "message"

解决方案

would it be considered best practice to just do:

git add .

git commit -am "message"

anyway?

No, there is no such "best practice". As long as you do not want to include any untracked files, git add + git commit -m and git commit -am will do exactly the same.

There are two situations where you need to to use git add:

• if you want to include untracked files, and
• if you do not want to commit everything that changed

The second point in particular is the reason many people recommend against always using commit -a: After working on code for a while, you often have several different types of changes in your working copy (the bugfix you were working on, some unrelated renaming, some temporary changes for debugging...). commit -a risks putting too much into one commit - in these cases selective use of git add is better.

But if you are certain you want to commit everything you changed, go ahead and use git commit -a.
