chown Command Examples in Linux¶

Introduction¶

These examples show practical ways to use chown on a Linux terminal. Each example is written so you can adapt it for administration or troubleshooting.

Example 1: Basic Usage¶

sudo chown alice report.txt

This is the simplest form of the command and is a good starting point before adding options.

Example 2: Common Admin Task¶

sudo chown apache:apache /var/www/html/index.html

This example reflects a common task on RHEL, Rocky Linux, AlmaLinux, or similar systems.

Example 3: Useful Option¶

sudo chown -R deploy:deploy /srv/app

This option helps narrow the result, change behavior, or handle a more realistic target.

Example 4: Real-World Scenario¶

sudo chown :developers shared.txt

Use this pattern when the task moves beyond a single basic command.

Example 5: Verification¶

ls -l report.txt

Example output:

-rw-r--r-- 1 alice admins 1200 May 30 10:00 report.txt

Common Mistakes¶

• Running recursive chown from the wrong directory and changing too much.
• Changing only the user when the service also requires a specific group.
• Using a username or group name that does not exist on the target system.

Quick Reference¶

sudo chown alice report.txt
sudo chown apache:apache /var/www/html/index.html
sudo chown -R deploy:deploy /srv/app
sudo chown :developers shared.txt
ls -l report.txt
