Git (TortoiseGit) - How to revert a single file to

问题:

When using Git with TortoiseGit: Does somebody know how to revert a single file(or a complete repository) to a previous revision?

For example I have a repository containing multiple files. One file exists in three revisions (1 ; 2 ; 3). Now I want to change from revision 3 back to 2.

TortoiseGit offers a "Revert" function in the "Show log" dialog which allows to jump back to a specific revision, but this will revert your whole repository instead of a single file.

Also once I have reverted something, I don't have a clue how to undo the revert and jump back to the newest revision.

In TortoiseGit the answer is to right-click the project folder and click Show Log, then right-click the change you want to roll back to and click Switch/Checkout to this... . It will let you then proceed from that weird place in the commit stack, or branch in case you plan to commit and want things to stay sane.

回答2:

From the command line: git checkout is probably what you want.

The documentation shows an example of:

$ git checkout master~2 Makefile

to revert Makefile to two revisions back in the master branch

From within TortoiseGit (via Windows Explorer) it looks like you can do this with the following steps:

Navigate in Explorer to the folder where the file is.

Right-click on the file you want to revert, choose Show log from the TortoiseGit context menu

In the top section ("graph") select the revision that has the version of the file you want to revert to

In the third section (file list) right-click the file and choose Revert to this revision

You should get a message like 1 files revert to e19a77

It is also possible to get a specific file:

• Right-click on the file
• Choose the menu item: Git Show Log

TortoiseGit show a dialog with a list of all revisions

• Click on the prior revision (2)

In a list in the bottom of the dialog it shows all the files associated with the commit

• Find the file you are looking to view
• Right-click on that file and Save Revision To
• This will save that previous revision of the file with the commit number concatenated on the file

For example: - original file is file.txt - revision 2 will save as file-67b51a8.txt

I'm using TortoiseGit v2.2.0.0

Suppose the working tree is clean and you want:

1. Checkout some file(s) of its previous revision
2. Testing
3. Revert to current revision

---

1. Checkout some file(s) of its previous revision

   (a) Right click the file you want to revert and Show Log for that file

   

   (b) Right click the file in file list and perform Revert to parent revision

   

   

   (c) repeat (a), (b) until you get all files you want.

   

2. Testing

3. Revert to current revision

   (a) perform Revert... in context menu of explorer

   This way, you can choose the file(s) you want to revert.

   (b) or this quick way: perform Reset Hard in Log dialog

   This way, all changed files revert. (=> Lost all working dir changes)

For Tortoise Version 2.3.0:

You can do it in several ways, but fastest i think is that:

1. Right click on the file
2. Click the menu option "Diff with previous version"
3. Right click on the left (previous) version of file
4. Click the menu option "Use this whole file"
5. Save the changes (ctrl+s)
