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
