How do I run a script every 5 minutes in Linux crontab?

Add "0 * * * * /usr/bin/php /var/www/script.php >> /var/log/cron.log 2>&1" to your crontab file.

0 * * * *frequency

Every Hour (0 * * * *)

S'exécute au début de chaque heure (:00). Standard pour les sauvegardes horaires et la rotation des logs.

0 * * * *

Standard 5-part cron syntax: Minute [0-59] | Hour [0-23] | Day of Month [1-31] | Month [1-12] | Day of Week [0-6]

Paste this line into your system crontab file (crontab -e):

0 * * * * /usr/bin/php /var/www/script.php >> /var/log/cron.log 2>&1

Equivalent AWS CloudWatch / EventBridge scheduled rule syntax:

cron(0 ? ? ? ?)
