What is root's MAILTO set to?
Have you read root's mail?
What is the cron job's stdout set to?

So it is all down to the difference in ENVIRONMENT between when the
script is run as CRON and when the script is run at the user shell
interface.

And that *is* what I told him in my own reply. He did not specify the
path to the executable "run-parts", which resides in "/usr/bin" on my
system, and cron runs Bash (or whatever the default shell is) in
non-interactive mode, in which case his environment definition -
including the value of $PATH - will not get sourced and a minimal
environment is used.

On legacy systems ie Unix it will be Bourne Shell,
and increasingly on Linux systems it will be Dash.

So cron script writers should avoid using bashisms in
their scripts.

me

yes, checked just in case, but nothing there -as it gets redirected to me
too

I have MAILTO set to me, so it should go there.
