To attach to a running job (job $JOBID)

```auto
srun --pty --jobid $JOBID /bin/bash

```

This will run inside the cgroup (CPU, RAM etc.) of the running job.

If you want to see the processes you can run top directly via

```auto
srun --pty --jobid $JOBID top

```

For jobs with multiple nodes you need first find the node you want to attach to via

```auto
scontrol show job $JOBID |grep NodeList

```

Then use the `-w` switch to specify the node ($NODE)

```auto
srun --pty --jobid $JOBID -w $NODE /bin/bash

```
