file permissions on joblog

[Rob Sargent]

I'm using GNU Parallel behind not one but two intermediaries. I submit 
to the first, the first wraps the jobs in a "slurm" script and submits 
the jobs to the second (the slurm host).

The jobs run on the slurm host under the account of the first 
intermediary, username and group not accessible to me.  I would like to 
be able to view the --joblog file but its permissions are 640.

I'm currently re-using pieces I normally run directly at the slurm host 
and don't have this problem - the jobs are mine.  It's quite slow to 
debug tests like making the joblog prior to gnu parallel call and chmod 
a+rw, but assume parallel would re-write the file from scratch rather 
than append to it.

Or perhaps I can use "--resume" from the outset, but surely that relies 
on a non-empty joblog?  Could I fake the first line?

Thanks
