If a you specify a job ID:
- You can get read messages of jobs submitted by other users, but you cannot read data files attached to jobs submitted by other users.
- You can only read data files attached to your own jobs.
- Root and LSF administrators can read messages of jobs submitted by other users.
- Root and LSF administrators cannot read data files attached to jobs submitted by other users.

Default: 0
-a file_name

for the file you are copying the attachment to. If the file already exists, -a
overwrites it with the new file.

attachments are saved in LSB_SHAREDIR/info/.
