Linux CLI - File Permissions and Ownership

To ensure a shared directory /shared causes new files to inherit the directory's group and prevents users from deleting files they do not own, which special permissions should be set?

ASet only the sticky bit on the directory

BSet the setuid bit on the directory and enable the sticky bit

CSet the setgid bit on the directory and enable the sticky bit

DSet only the setgid bit on the directory

Step-by-Step Solution

Solution:

Step 1: Understand setgid on directories
Setgid on a directory causes new files to inherit the directory's group ownership.
Step 2: Understand sticky bit on directories
The sticky bit restricts file deletion to the file owner or root.
Step 3: Combine permissions
Setting both setgid and sticky bit achieves the desired behavior.
Final Answer:
Set the setgid bit on the directory and enable the sticky bit -> Option C
Quick Check:
Setgid for group inheritance + sticky bit for deletion control [OK]

Quick Trick: Setgid + sticky bit for shared directory control [OK]

Common Mistakes:

MISTAKES

Using setuid instead of setgid on directories
Setting only sticky bit without setgid
Assuming setgid controls file deletion
