Certified Ethical Hacker (CEH v11) — Question 336

To hide the file on a Linux system, you have to start the filename with a specific character.
What is the character?

Answer options

• A. Tilde (~)
• B. Underscore (_)
• C. Period (.)
• D. Exclamation mark (!)

Correct answer: C

Explanation

On a Linux system, filenames that start with a period (.) are treated as hidden files. The other options do not serve this purpose; for example, a tilde (~) is commonly used for home directories, while an underscore (_) and an exclamation mark (!) have no special significance in hiding files.
