Linux CLI - File Permissions and Ownership

You want to change the owner to carol and the group to staff for all files and folders inside /data/project recursively. Which command should you use?

Achown -r carol:staff /data/project

Bchown carol staff /data/project -R

Cchown carol:staff /data/project

Dchown -R carol:staff /data/project

Step-by-Step Solution

Solution:

Step 1: Understand recursive ownership change
The -R option applies ownership changes to all files and folders inside the given directory recursively.
Step 2: Check correct syntax for user and group
Use user:group format to set both owner and group at once.
Step 3: Verify options order and spelling
chown -R carol:staff /data/project uses -R correctly and the right syntax. chown carol staff /data/project -R has wrong order and missing colon. chown carol:staff /data/project misses recursive flag. chown -r carol:staff /data/project uses lowercase -r which is invalid.
Final Answer:
chown -R carol:staff /data/project -> Option D
Quick Check:
Use -R and user:group for recursive ownership [OK]

Quick Trick: Use -R and user:group to change ownership recursively [OK]

Common Mistakes:

Forgetting the -R flag for recursion
Using lowercase -r instead of -R
Separating user and group without colon
Placing options after the path
