On Mac OS X the sed command with "-i" option takes a file extension parameter.
The original file will be saved to a new file with the supplied extension, and
any changes are applied to the old file. For example, if the second sed comand
above were changed to:
sed -i .bak "/$1/d" hosts.deny
... the original contents of the hosts.deny file would be saved as
hosts.deny.bak, while the supplied address would be removed from hosts.deny.
