Thanks to so many answer.
SUN cron daemon will NOT re-read /avar/spool/cron files withour use "crontab
-e".
Redhat linux will re-read /var/spool/corn every minutes. That is reason why
LINUX work on both way.
DOC from LINUX man parge:
Additionally, cron checks each minute to see if its spool directory's
modtime (or the modtime on
/etc/crontab) has changed, and if it has, cron will then examine
the modtime on all crontabs and reload those which have changed. Thus cron
need not be restarted whenever a crontab file is modified. Note that the
Crontab(1) command updates the modtime of the spool directory whenever it
changes a crontab.
