Description Federico Baldassarre 2024-07-30 10:36:45 MDT 
The expansion of %A in sacct --expand-patterns is incorrect for job arrays. It expands to the unique id of the job and not to the array id.

If the job is running, scontrol gives the actual path that the job is writing to.



Example with a job array (JobId=4222747 ArrayJobId=4222555 ArrayTaskId=10):

```
sacct --job 4222555_10 --format=StdOut%200 --expand-patterns
path/to/logs/4222747_10_0_log.out

sacct --job 4222555_10 --json | jq -r '.jobs[0].stdout'
path/to/logs/%A_%a_0_log.out

sacct --job 4222555_10 --json | jq -r '.jobs[0].stdout_expanded'
path/to/logs/4222747_10_0_log.out

scontrol show job 4222555_10 | grep -i stdout
StdOut=path/to/logs/4222555_10_0_log.out
```



Example with a regular job (JobId=4222523):

```
sacct --job 4222523 --format=StdOut%200 --expand-patterns
path/to/logs/4222523_0_log.out

sacct --job 4222523 --json | jq -r '.jobs[0].stdout'
path/to/logs/%j_0_log.out

sacct --job 4222523 --json | jq -r '.jobs[0].stdout_expanded'
path/to/logs/4222523_0_log.out

scontrol show job 4222523 | grep -i stdout
path/to/logs/4222523_0_log.out
```
