Version control is important for tracking changes to code over time, and Subversion (SVN) is a popular version control system. To check the revision of an SVN repository, you can use the “svn info” command. This command will print out information about the repository, including the current revision number.
The revision number is important because it allows you to track changes to the code over time. You can use the revision number to compare different versions of the code, or to revert to a previous version if necessary. To check the revision number of a file, you can use the “svn log” command. This command will print out a list of all the changes that have been made to the file, including the revision number for each change.
