hello!

how does linux flag a file as mfu, lfu, etc.?

is there basically a counter that counts up? or does the file index change if a file is or is not used often?

thank you for your input.

Hi,

And welcome to LQ!

And sorry, I have no idea you're talking about with mfu, lfu and the
likes... can you please elaborate on what you're trying to find out?

Hi!

I am starting to think Linux simply does not have this functionality.

Is there some place in the file system where a file is flagged as least/most frequently used?

When Norton Utilities tells me "these are the files most frequently used by your OS", is it getting that information from Linux? Or is it getting that information from somewhere like the BIOS, say, or some place else?

Put another way, can I write an application that looks for most frequently used files just like it would look for files that were created by me or created yesterday? Is there a system call for that? Or do I need to write that myself? How is NU doing it?

Thanks.

Depending on your distro you may want to use FAM and a FAM-Monitor.

Personally I always turn it off because of the system-overhead it
causes. The luxury of knowing what file has been accessed how often
isn't worth the constant CPU load (not to me, anyway - I can't understand
people who monitor their machines in a crippling way )

To find files created by my in a given time I'd use find.

find -user myself -atime -1
(or -ctime or -mtime, depending on what I'm after; the -1 means younger
than 24 hours [1 day]).
