Linux CLI - File and Directory Operations

You want to create empty files named log1.txt, log2.txt, ..., log5.txt quickly using a single command. Which command achieves this?

Atouch log*.txt

Btouch log{1..5}.txt

Ctouch log1.txt log2.txt log3.txt log4.txt log5.txt

Dtouch log[1-5].txt

Step-by-Step Solution

Solution:

Step 1: Understand brace expansion
The syntax log{1..5}.txt uses brace expansion to create multiple filenames from 1 to 5.
Step 2: Evaluate other options
log[1-5].txt matches single characters in brackets, not ranges. Listing all files manually works but is long. log*.txt matches existing files, not create new ones.
Final Answer:
touch log{1..5}.txt -> Option B
Quick Check:
Brace expansion creates multiple files fast [OK]

Quick Trick: Use brace expansion: touch file{1..5}.ext [OK]
