[Message part 1 (text/plain, inline)]
Good morning,

I noticed that the split command doesn't update the file modified time of
the destination split files as it writes to them, it only updates the file
modified time when the split completes.

Is this a known issue?

Cheers,
Tim

split doesn't explicitly modify timestamps at all.  The behavior you are
seeing is solely a function of your kernel and filesystem options, in
relation to the timing between coreutils flushes and closes each file
that it has written.

It's normal behavior.  Even if there were something to patch, you would
have to get it fixed in the kernel, not in split.

Therefore, I'm closing this as not a bug, although you should feel
welcome to ask further questions as needed on this thread.
