You should do
gem5.opt configs/example/se.py --help
It's clearly documented there how to do this.
-i INPUT, --input=INPUT
Read stdin from a file.
--output=OUTPUT Redirect stdout to a file.
--errout=ERROUT Redirect stderr to a file.
So for your case....
gem5.opt configs/example/se.py --cmd=milc --input=su3imp.in
