Linux CLI - System Administration

Abackup_dir="/backup/$(date +%Y%m%d)"; cp -r /etc "$backup_dir"

Bbackup_dir="/backup/date"; cp -r /etc $backup_dir

Cbackup_dir="/backup/$(date)"; cp /etc $backup_dir

Dbackup_dir="/backup/$(time +%Y%m%d)"; cp -r /etc $backup_dir

Step-by-Step Solution

Solution:

Step 1: Understand date command usage
Using $(date +%Y%m%d) creates a folder name like 20240601 for today.
Step 2: Check copy command correctness
cp -r copies directories recursively; quotes protect spaces in path.
Final Answer:
backup_dir="/backup/$(date +%Y%m%d)"; cp -r /etc "$backup_dir" -> Option A
Quick Check:
Timestamped backup folder = date +%Y%m%d [OK]

Quick Trick: Use date +%Y%m%d for timestamped folder names [OK]

Common Mistakes:

Using 'date' without +format
Copying without -r for directories
Using 'time' command instead of 'date'
