here we go again...
1. daca pui comenzile tale in /var/spool/cron/root (metoda recomandata este sa
te faci root si sa dai comanda 'crontab -e'), sintaxa este
* * * * * /root/bin/rescanscsi
(FARA root)
2. daca pui comenzile in /etc/crontab (care este global, pentru toti userii),
sintaxa este
* * * * * root /root/bin/rescanscsi
^^^^- userul cu care este rulata comanda
3. daca folosesti /etc/cron.{hourly,daily,etc} se pune in directorul
respectiv direct scriptul de executat sau link simbolic catre el
4. */1 este inutil. * e acelasi lucru (orice numar se imparte exact la 1,
right?)
