well, this was the first thing i tried but i have a null command

[root at alien ~]# scontrol show job 2794270
JobId=2794270 JobName=AliEn.4865.575

    Power=

this is slurm 19.05.2 and my purpose is only for running jobs

moreover it's not clear to me what are the steps of job submission and 
the processes involved ..

it seems to be that slurmstepd (with identification of jobid.batch) 
start a slurm_script that i think that is the actually submitted script

the job start a srun with a script (specified in submiited script)
and at the moment i get an slurmstepd[jobid.0] where this is run

so, at this moment it would be enough if given a job id i can get the 
submission script...

is there a way to do it? (beside get the node from squeue and then ssh 
on node and ps grep?)

Thank you!
Adrian
