SYNOPSIS
sattach [options] <jobid.stepid>

OPTIONS
-h, --help
Display help information and exit.
--input-filter[=]<task number>

--error-filter[=]<task number>
Only transmit standard input to a single task, or print the
standard output or standard error from a single task. The
filtering is performed locally in sattach.
-l, --label
Prepend each line of task standard output or standard error with
the task number of its origin.
--layout
Contacts the slurmctld to obtain the task layout information for
the job step, prints the task layout information, and then exits
without attaching to the job step.
--pty Execute task zero in pseudo terminal. Not compatible with the
--input-filter, --output-filter, or --error-filter options.
Notes: The terminal size and resize events are ignored by
sattach. Proper operation requires that the job step be
initiated by srun using the --pty option. Not currently

be displayed.
-u, --usage
Display brief usage message and exit.

override environment variables settings.
SLURM_CONF The location of the Slurm configuration
file.
SLURM_EXIT_ERROR Specifies the exit code generated when a
Slurm error occurs (e.g. invalid options).
