What is doing this?

[Mike McGrath]

We've got a cron job that creates the fedorahosted webpage.  It produces
(on occasion) this output:
========== START ==============
...... done.
...... done.
========== END OUTPUT =========

I've been poking at it for a bit and I just don't know what is causing
that, so to the list I came.  Anyone have any bright ideas?  I've attached
the script.  My first inclination is that it's the make.  But what in it
is causing this to happen sometimes but not every time?

Now with an actual attachment.

This is just a random guess, but the text reminds me of:

receiving file list ... done

from rsync.  I wonder what could cause this to be printed if it were
rsync...

Thanks,

Yes, rsync always do that:

building file list ... done
...
receiving file list ... done

This makes me wonder if rsync is sending part of that message to  
stderr. I tried to reproduce it but have been unable to.  It just  
sortof happens sometimes.

I tried this and the only thing that appeared in /tmp/stderr was the 
remote host's SSH banner:

rsync --rsh=ssh -avHn . remotehost:foo/  2> /tmp/stderr 1> /tmp/stdout

The "file list ... done" lines all appeared in /tmp/stdout.

If memory serves me, cron jobs do not get their own tty.
tty based file handels can get flaky in cron jobs.
I have run across situations in Solaris and AIX,
where the the last filehandle accessed --redirected to /dev/null or not-- by
a cron script is the one that gets the output.
I am not sure why or what causes it.

I would force the STDOUT and STDERR of each command in the job to
$0.$DATESTAMP log files until the error(s) reproduce.
that way it can "hopefully" be determined where it is comming from and
suppression or remediation can
take place.
