cron & tab

If the cron.allow file exists, then you must be listed therein in order
to be allowed to use this command. If the cron.allow file does not
exist but the cron.deny file does exist, then you must not be listed in
the cron.deny file in order to use this command. If neither of these
files exists, only the super user will be allowed to use this command.

targetpw If set, sudo will prompt for the password of the user specified by the -u flag (defaults to root) instead of the password of the invoking user. Note that this precludes the use of a uid not listed in the passwd database as an argument to the -u flag.
