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.

deny$ deny 結尾
^at at 開頭
