  • -- -- ignore previous arguments after reloading data
  • -e x -- evaluates the expression x
  • -h -- displays the usage message
  • -n -- print no input prompts
  • -q -- suppresses loading of init file 'init.m2'
  • -s -- stops execution if an error occurs
  • -silent -- don't print the startup banner
