What on earth do you use atime for? Personally, the last time I ever needed to worry about atime was in the 1990s, and it was very easy to replace.

I use atime to check whether some complex software really does access the files that I think it does.

Wouldn't "strace -f" be handier for that kind of thing? With that you notice also a lot of other stuff that the SW does.

Strace-account script gives an overview of file accesses in the strace output:

It would not be handier exactly because it tells me a huge amount of other stuff the software does and that I am not interested in.

And how is that handier than just doing "stat <file>"?
