Submit Multiple Jobs at Once: -f <file>

Prepare a file with one command on each line. Empty lines are ignored and lines that begin with # are considered comments.
```
# Example of file used to submit multiple jobs at once.
sleep 10
sleep 11
sleep 12
sleep 13 
```
Use the option -f to specify the command file, as in the following example:
```
% nc run -f commandFile
```
All jobs submitted with this method share the same environment, the same resources, and are scheduled at the same priority level. Each job has its own ID.
