Git (TortoiseGit) - How to revert a single file to a previous revision and then undo the revert?

Question

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.

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
