Linux CLI - Searching and Finding

You need to remove files from /archive that were last modified over 15 days ago, but leave newer files intact. Which command safely accomplishes this?

Afind /archive -mtime +15 -type f -delete

Bfind /archive -mtime -15 -type f -delete

Cfind /archive -mtime 15 -type f -exec rm {} \;

Dfind /archive -mtime +15 -type f -exec rm {} \;

Step-by-Step Solution

Solution:

Step 1: Identify files older than 15 days
The -mtime +15 option selects files modified more than 15 days ago.
Step 2: Ensure only files are targeted
The -type f restricts the search to regular files.
Step 3: Remove files safely
-exec rm {} \; executes the remove command on each found file safely.
Final Answer:
find /archive -mtime +15 -type f -exec rm {} \; -> Option D
Quick Check:
Check for files older than 15 days and confirm deletion command [OK]

Quick Trick: Use -mtime +N with -exec rm for files older than N days [OK]

Common Mistakes:

Using -mtime -15 deletes files modified within last 15 days
Using -mtime 15 finds files modified exactly 15 days ago
Using -delete without confirming file type may remove directories
