Afick

Developed in Perl, Afick is a command-line application you can use to monitor your PC's filesystem for changes. It can help you identify intrusions and verify file integrity.

Since it's a console tool, it's dedicated to PC users who prefer Command Prompt to the graphical interface, as they can accomplish tasks quicker by just entering some command-line arguments.

The setup operation is fast. It's quite obvious that Afick hasn't received updates for a long time, due to the fullscreen installer with a gradient color in the background. It shouldn't give you any kind of trouble, since it doesn't contain special options or third-party offers. However, you must have Perl installed.

As far as program options are concerned, it's possible to initialize the hash.dbm database, check and clean the configuration settings, compare and update the hash.dbm file, and print the database contents with or without using filters.

Moreover, you can display macros, aliases, rules, a list with file extensions sorted by numbers, dangerous files (e.g. SUID, SGID, world writable), statistics about the file size, and a chronological list of modified files.

When it comes to the log details with filesystem modifications, you can check out the total number of scanned, changed, new and deleted files, along with the time and date of the checkup.

It worked smoothly in our tests, without triggering the OS to hang, crash or prompt error dialogs. CPU and RAM usage was minimal, so it didn't hamper system performance.

To sum it up, Afick comes packed with practical options to monitor your filesystem for changes, and it should meet the requirements of many advanced PC users. Plus, it's free.
