Link: fslogger
fslogger is a user-space program that subscribes to the same file system event notification mechanism as the Spotlight metadata server.
Once active, fslogger will wait for change notifications to arrive from the file system layer in the kernel. The various file system operations that are communicated to fslogger (and other subscribers such as Spotlight, specifically the metadata server) include:
- File creation
- Folder creation
- File or folder deletion
- Changes to the stat structure (for example, a permission change)
- Renaming of a file or a folder
- Content modification
- Content exchange between two files
- Finder information changes
- Change of ownership
