How to delete file with special characters

Sometimes some people create a file with special character like "-s" in the filename.

If you use

 rm -s 

or

 rm "-s" 

You will get an error that '-s' is not a valid parameter.

You can add a "--" before the filename.


Example:
Display its content：

cat -- -s

List the file:

ls -l -- -s

Delete the file:

rm -- -s
