$ sattach jobid.stepid

$ sattach --input-filter 0 jobid.stepid

$ sattach --output-filter 0 jobid.stepid

$ sattach --error-filter 0 jobid.stepid

sattach [options] jobid.stepid

sattach attaches to a Slurm job step's input/output streams, allowing you to interact with a running job. It redirects the stdout, stderr, and stdin of a Slurm job step to the current terminal.

jobid.stepid

The job ID and step ID to attach to (format: jobid.stepid)

Use the current console's input as stdin to the specified task

Only redirect stdout of the specified task

Only redirect stderr of the specified task

Prepend task number to lines of output

Only the job owner can attach to a job step. The job must be in a running state. Not all MPI implementations support attachment.

sattach is part of the Slurm workload manager, providing job scheduling and resource management for HPC clusters.
