Usage: donkey -n <NUM> [OPTION]... <INPUT FILE> 

 -o <FILE>	 Output file
 -n <NUM>	 Output all lines except the last n number of lines
 -e		 Edit input file. Overwrites the original file. Cannot be used with -o

There is no default number of lines to be removed; therefore, the -n option must be specified. The output can
be saved to file using either -o OR -e. -o will overwrite the specified output file if it already exists or 
create the file if it does not. -e will overwrite the original input file with the output of the command.
If neither output option is selected, then the output is written to stdout.
