-f<data-file>
The data-file is a filename that contains lines of data to be matched (or not) against one or more
patterns. When the program is run, it will prompt you for a wild-card pattern, then apply it one
line at a time against the data in the file. Each line that matches will be printed preceded by
its line number. You will then be prompted again for another pattern.
Enter an empty line for a pattern to terminate the program. You can print only lines that do not
match by using the -n option, and you can suppress printing of line numbers with the -l option.
-n Print lines that do not match
-l Suppress lines numbers.
-i use case insensitive match.
