Linux under SVN revert to a version __linux

There are two ways to achieve this:

Method 1: Using the SVN merge
1 First SVN up, to ensure that updates to the latest version, such as 20;
2 then use the SVN log to view the history changes and find the version to restore, such as 10. If you want a more detailed understanding of the situation, you can use SVN diff-r 10:20 [file or directory];
3 rollback to version number 10:SVN merge-r 20:10 [file or directory], note the order between version number, this is called reverse merging;
4 View the current working version of the file, such as Test.cpp and version Number 10 file differences: SVN diff-r a test.cpp, the difference is manually changed;
5 if no difference, then submit: SVN ci-m "back to R 10,xxxxx" [file or directory]. A new version, such as 21, is generated in the SVN library.

Method 2: With SVN up
The first 2 steps, such as Method 1, then direct SVN up-r 10. The current working version is version 10. Note, however, that the SVN library will not generate a new version, the next time the local SVN up, or will return to the previous version.
