This happens because all arguments that start with a '-' are parsed as
an option.  In this can -file means the same as -f -i -l -e.  The ls
command does not know the argument '-e'.

If you make the file -fil instead of -file you can see better what
happens.

To prevent ls from parsing the argument a options you can use "--" as
you can read in the documentation.  For example:

ls -- *file
