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

Add "0 9 * * 1-5 /usr/bin/php /var/www/script.php >> /var/log/cron.log 2>&1" to your crontab file.

0 9 * * 1-5daily

At 9:00 AM Mon-Fri (0 9 * * 1-5)

Triggers at 9:00 AM Monday through Friday. Standard for business morning report dispatches.

0 9 * * 1-5

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 9 * * 1-5 /usr/bin/php /var/www/script.php >> /var/log/cron.log 2>&1

Equivalent AWS CloudWatch / EventBridge scheduled rule syntax:

cron(0 9 ? ? 1-5)
