在Git中，有没有办法让“友善”任意提交的名称？ [英] In Git, is there a way to get the "friendly" name for an arbitrary commit?

问题描述

在Git中，有很多方法可以引用一个提交，包括完整的SHA散列或散列的缩写形式（比如前6个字符左右）。您还可以使用友好语法来命名提交，例如HEAD，HEAD ^，HEAD ^^，HEAD〜3等等。

如果我使用 git-show-branch，那么在Git中有一个工具可以为所述提交找到一个友好的名字？

，我以友善的形式得到修订列表，所以我觉得必须有一种方法......我找不到一个工具来完成它。

解决方案

您可以使用git name-rev来获取您询问的表单。这种形式的一个问题是，相对于一个分支，它不是一个永久名称。因此，另一种方法是git describe，它根据给定提交的标签之前的距离来产生另一个友好名称。

例如：$ /

b
$ b

  srh @ devo16：〜/ src / git< master> $ git name-rev 3cd7388 
 3cd7388 master〜2 
  

但是在我做了git pull之后，master〜2可能意味着别的东西。相比之下：

  srh @ devo16：〜/ src / git< master> $ git describe 3cd7388 
 v1。 6.3.1-153-g3cd7388 
  

现在v1.6.3.1-153-g3cd7388是一个永久名称。当然，它仍然有点长（尽管你可以通过指定--abbrev = 4来缩短最后的散列位），但是它告诉我们3cd7388在版本1.6.3.1之后有153个变化。

In Git, there are numerous ways to refer to a commit, including the full SHA hash or a shortened form of the hash (say, the first 6 characters or so). You can also name commits using a "friendly" syntax, like HEAD, HEAD^, HEAD^^, HEAD~3, and so on.

Given an arbitrary commit in SHA hash form, is there a tool in Git to find a "friendly" name for said commit?

If I use git-show-branch, I get a list of revisions in "friendly" form, so I feel like there must be a way...I just can't find a tool to do it.

解决方案

You can use "git name-rev" to get the form you are asking about. One problem with that form is that, being relative to a branch, it isn't a permanent name. So an alternative is "git describe" which produces an alternative friendly name based on how far ahead of a tag a given commit is.

For example:

srh@devo16:~/src/git <master>$ git name-rev 3cd7388
3cd7388 master~2

But then after I do a "git pull", master~2 could mean something else. By contrast:

srh@devo16:~/src/git <master>$ git describe 3cd7388
v1.6.3.1-153-g3cd7388

Now "v1.6.3.1-153-g3cd7388" is a permanent name. Of course, it's still a bit long (although you can shorten the hash bit on the end by specifying "--abbrev=4" for example) but it communicates that 3cd7388 is 153 changes after version 1.6.3.1.
