Linux CLI - Searching and Finding

You want to find all files larger than 5MB in /home/user and change their permissions to 644. Which command correctly uses find with -exec to do this?

Afind /home/user -size +5M -exec chmod 644 {} \;

Bfind /home/user -size +5M -exec chmod 644 {} ;

Cfind /home/user -size +5M -exec chmod 644 \;

Dfind /home/user -size +5M -exec chmod 644 {}

Step-by-Step Solution

Solution:

Step 1: Understand size filter and command
-size +5M finds files larger than 5MB. chmod 644 {} changes permissions of each found file.
Step 2: Confirm correct -exec syntax
The command must end with \; to mark the end of the -exec action. find /home/user -size +5M -exec chmod 644 {} \; correctly includes this.
Final Answer:
find /home/user -size +5M -exec chmod 644 {} \; -> Option A
Quick Check:
Use -exec with {} and end with \; [OK]

Quick Trick: Use {} for file and end -exec with \; [OK]

Common Mistakes:

Omitting {} placeholder
Missing backslash before semicolon
