Apache Subversion, usually abbreviated to SVN, is an open source version control system. Subversion was developed by CollabNet Inc in 2000 and is now a project of the Apache Software Foundation. It is also part of a rich developer and user community.

Compared with RCS and CVS, SVN adopts branch management system, and its design goal is to replace CVS. Most of the free version control services on the Internet are based on Subversion.

When we want to discard changes to the file, we can use the SVN revert command.

The svn revert operation will undo local changes in any file or directory.

We modify the file readme to check the file status.

Root@runoob:~/svn/runoob01/trunk# svn statusM readme

At this time, we find that the modification error, to undo the modification, through the svn revert file readme to return to the unmodified state.

Root@runoob:~/svn/runoob01/trunk# svn revert readme Reverted 'readme'

Check the status again.

Root@runoob:~/svn/runoob01/trunk# svn status root@runoob:~/svn/runoob01/trunk#

After the revert operation, the readme file is restored to its original state. The revert operation can restore not only a single file, but also an entire directory. Restore the directory with the-R command, as follows.

Svn revert-R trunk

But what if we want to restore a committed version.

In order to eliminate an old version, we must undo all changes in the old version and submit a new version. This operation is called reverse merge.

First, find the current version of the repository, which is now version 22, and we need to undo it back to the previous version, such as version 21.
