monitor changes to (configuration) files
changetrack automatically monitors changes to a set of files. If the files are modified one day and the machine stops working correctly some days later, changetrack will provide information on which files were modified and thus help locate the problem.
If you tell changetrack to use either the line editor ed (the default) or The GNU Revision Control System (RCS), you can recover files to any previous stage. If you do not want to install Perl, try out the filetraq or diffmon package.
changetrack is a filesystem watch, similar to etckeeper.
