I think you want <code>hg revert -r&lt;rev&gt; &lt;file&gt;</code> (this will change that file to be as it was at the given revision).

blocks|key|1137487|text|正如djc所说，revert修改了一个文件，以匹配先前的修订。如果您不希望它就位，您可以使用hg+cat+-r+revisionid+filename+(当然，替换为修订号和文件名)，它会将文件输出到标准输出，适合于重定向到您喜欢的任何位置。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1137488|entityMap^0|8|6|1A|T|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

As djc said <code>revert</code> alters a file in place to match a prior revision. If you want it not in place you can use <code>hg cat -r revisionid filename</code> (substituting revisionid and filename of course) which will output the file to stdout, suitable for redirecting anyplace you'd like.

blocks|key|1137533|text|hg+revert确实解决了这个问题。但我认为，你对更广泛的事情感到困惑，而不是简单地回答你的问题，并希望尝试更全面地回答。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1137534|hg+update是一个完整的存储库命令，不会对单个文件起作用。它在这方面与subversion+svn+update不同。如果执行hg+--help+update，您可以看到情况就是这样，因为该命令没有接受文件参数。它可用于将整个存储库移动到特定快照，但不能用于仅对一个文件执行此操作。|1137535|如果键入hg+--help，您将看到一个命令列表。这是一个相当大且有些令人生畏的清单，但如果你通读它，你会发现这一行：|1137536|revert+++++++restore+individual+files+or+directories+to+an+earlier+state|code-block|syntax|javascript|1137537|现在，如果您只是想要最后一个状态用于比较，那么您可能会对另一个命令感兴趣，那就是hg+cat。这将允许您打印出任何特定修订版的文件内容。然后，您可以将其输出重定向到其他文件中。然后，您可以将文件的先前已知良好版本和旧版本并排进行比较。|1137538|Mercurial有一个单独的update命令的原因是，在Mercurial中可以做一些在Subversion中不可能做的事情。您可以update到较早的版本，进行更改，然后提交。这将创建一个分支。update命令还可以更改当前工作目录的父修订版本，并将该目录中所有文件的内容更改为父修订版本的版本。|1137539|这意味着revert更改了一个文件的内容(甚至是整个存储库，如果您为命令提供了正确的参数)，但保持当前工作副本的父修订不变。|1137540|您可以使用hg+parents命令查找当前工作副本的父修订(或合并时的修订)。|1137541|在Subversion中，修订是一个严格的线性级数。Mercurial可以轻而易举地创建分支，而且它们几乎同样容易合并。修订形成了DAG，而不是严格意义上的线性级数。|1137542|entityMap^0|0|9|0|0|9|1D|A|1U|G|0|4|9|0|0|14|6|0|F|6|1V|6|2R|6|0|4|6|0|5|A|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|13|8|@$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|1A|8|@$9|1B|A|1C|B|C]]|D|@]|E|$]]|$1|J|3|K|5|L|7|1D|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|1E|8|@$9|1F|A|1G|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|1H|8|@$9|1I|A|1J|B|C]|$9|1K|A|1L|B|C]|$9|1M|A|1N|B|C]]|D|@]|E|$]]|$1|S|3|T|5|6|7|1O|8|@$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|U|3|V|5|6|7|1R|8|@$9|1S|A|1T|B|C]]|D|@]|E|$]]|$1|W|3|X|5|6|7|1U|8|@]|D|@]|E|$]]|$1|Y|3|-4|5|6|7|1V|8|@]|D|@]|E|$]]]|Z|$]]

<code>hg revert</code> does indeed solve this problem. But I think that you are confused about a broader range of things than simply the answer to your question and want to try to answer more fully.

<code>hg update</code> is a whole repository command and will not work on individual files. It is unlike the subversion <code>svn update</code> in this way. If you do <code>hg --help update</code> you can see that this is the case because the command takes no file argument. It can be used to move your whole repository to a particular snapshot, but cannot be used to do that to just one file.

If you type <code>hg --help</code> you see a list of commands. It's a rather large and somewhat daunting list, but if you read through it, you'll find this line:

<pre><code>revert restore individual files or directories to an earlier state
</code></pre>

Now, if you just want the last state for comparison purposes, there is another command you may be interested in, and that's <code>hg cat</code>. That will allow you to print out the contents of a file at any particular revision. You can then redirect its output into some other file. Then you can have the previous known good version of your file and the old version to compare side-by-side.

The reason why Mercurial has a separate <code>update</code> command is that it is possible to do something in Mercurial that is impossible in Subversion. You can <code>update</code> to an earlier version, make changes, then commit. This will create a branch. The <code>update</code> command has the effect of also changing the parent revision of the current working directory as well as changing the contents of all the files in that directory to that parent revision's versions.

That means <code>revert</code> changes the contents of a file (or even the whole repository if you give the command the right arguments) but leaves the parent revision of the current working copy the same.

You can find out the parent revision (or revisions in the case of a merge) of the current working copy by using the <code>hg parents</code> command.

In Subversion revisions are a strictly linear progression. Mercurial creates branches at the drop of a hat, and they are almost as easy to merge. Revisions form a DAG, not a strictly linear progression.

To extract a specific revision of a specific file you can do this on Windows:

<pre><code>hg cat "&lt;FileToBeExtractedPath&gt;" -r 9 &gt; "&lt;ExtractionPath&gt;"
</code></pre>

Here, 9 is the revision number.

Or even better:

<pre><code>hg cat "&lt;FileToBeExtractedPath&gt;" -r 9 -o "&lt;ExtractionPath&gt;"
</code></pre>

I am new to Mercurial. Just cannot find the right command. Tried update/checkout with no luck. I am using local repository. Thanks

How to get a specific version of a file in Mercurial?

我对Mercurial是个新手。只是找不到合适的命令。已尝试更新/检出，但没有成功。我正在使用本地存储库。谢谢
