Most command line tools use a single argument containing `--` to indicate
"everything after this is a positional argument". E.g., grep takes a `-i`
option which asks it to be case insensitive. But what do you do if you want
your pattern to be `-i`? Without `--`, grep would think that it was an
option instead of the actual pattern to be searched for, so this is the
command line you use to get the desired result:

grep -- -i foo.txt
