Another useful format string – and again, this is if you mess up and don’t do a
reservation early enough (or your environment has no concept of a time limit) –
is this one:
squeue -o %u,%i,%L
Will show you username, job id, and remaining time – which is sometimes easier
to deal with than end date/time.
