Hi Tina,

sadly, this does not always work in version 20.11.x any more because of the
new non-overlapping default behaviour for job step allocations.

$ sbatch -n 1 --wrap="srun sleep 600"
Submitted batch job 2550804
$ squeue --me
     JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
    2550804  standard     wrap user01   R       0:06      1 n0326

$ srun --jobid=2550804 --pty /bin/bash
srun: Job 2550804 step creation temporarily disabled, retrying (Requested nodes are busy)

(and hangs forever untig Ctrl-C'ed ...)

^Csrun: Cancelled pending job step with signal 2
srun: error: Unable to create step for job 2550804: Job/step already completing or completed
$

This now needs --overlap option for both, the job allocation itself and the
srun command that attaches the shell, in order to always work as before. 

Best regards
Jürgen
