$ srun --jobid [job_id] --pty /bin/bash

srun [options] executable [arguments]

srun submits a job for execution or initiates job steps in real time. For interactive work, it creates an interactive session on compute nodes. It can also be used within batch scripts to launch parallel tasks.
The command handles resource allocation automatically, requesting nodes from the scheduler and launching the specified program across allocated resources.

Interactive jobs (--pty) may wait in queue for resources. Resource requests must fit within partition limits. Connection to existing jobs requires appropriate permissions.
