Linux CLI - File Permissions and Ownership

You ran chmod 755 myfile but ls -l myfile shows -rw-r--r--. What is the likely problem?

AThe chmod command syntax is incorrect

BYou forgot to specify the filename

CYou do not have permission to change the file mode

DThe file is a directory, not a regular file

Step-by-Step Solution

Solution:

Step 1: Understand chmod effect and output
chmod 755 should set execute permission, but output shows no execute bits.
Step 2: Identify permission issue
If permissions did not change, likely user lacks rights to modify file mode (not owner or no sudo).
Final Answer:
You do not have permission to change the file mode -> Option C
Quick Check:
chmod no effect = permission denied [OK]

Quick Trick: No change after chmod? Check your ownership rights [OK]
