How To make sure any file or folder created in /var/www/html gets automatically owned by www-data

Automatically Set Ownership to www-data Using incron

If you want to ensure that any file or folder created inside /var/www/html is automatically owned by www-data, you can use incron.

Incron works similarly to cron, but instead of running based on time schedules, it monitors filesystem events such as:

• File or directory creation
• File modifications
• Attribute changes
• File deletions

---

Step 1 — Install incron

Install incron using:

sudo apt-get install incron

---

Step 2 — Allow Root to Use incron

By default, not all users are allowed to use incron. You must explicitly grant permission.

Open the file:

sudo vim /etc/incron.allow

Add the following line:

root

Save and exit.

---

Step 3 — Configure incrontab

Edit the incrontab for root:

sudo incrontab -u root -e

Add this line:

/var/www/html IN_CREATE /bin/chown -R www-data:www-data /var/www/html/

Save and exit.

How It Works

With this configuration, whenever a new file is created inside /var/www/html, its ownership will automatically be changed to:

www-data:www-data

---

Explanation of the incron Rule

General format:

<directory> <event> <command>

Breakdown of the rule:

• /var/www/html → the directory being monitored
• IN_CREATE → triggers when a new file or directory is created
• /bin/chown -R www-data:www-data /var/www/html/ → command executed automatically

---

Important Notes

• The -R option applies ownership changes recursively to all contents inside the directory.
• If you only want to change ownership for the newly created file (not recursively), you should modify the command accordingly.
• Make sure the incron service is running:

sudo systemctl status incron

---

Summary

Using incron is a practical solution for:

• Automatically managing file ownership
• Monitoring filesystem events in real time
• Eliminating repetitive manual permission changes

Hope this helps 👍
