If what you’re after is to tell after the fact that a file has been accessed, you should look into auditd, or just turn on atime on your filesystem (note that this has been turned off for good reasons). You may even find that relatime does what you need: I think https://lwn.net/Articles/244829/ is still accurate. If you want to run a program the instant a file has been accessed, you will need to look into fanotify (and probably do some programming): see https://lwn.net/Articles/360955/ for details. These will let you know when a program is opened for reading: if you then want to know each time a program reads a byte, you’re pretty much out of luck: the mmap API means the OS doesn’t get to see precisely when a particular byte is read (if it’s already in cache). Hope this helps, James. -- E-mail: james@ | A wood-pigeon would, If a wood-pigeon could, aprilcottage.co.uk | But a wood-pigeon can’t, So it won’t. | A wood-pigeon could, If a wood-pigeon would, | But a wood-pigeon doesn’t want to.
