Correct answer: A. cat emp[!0-9]
- A. cat emp[!0-9]
- B. more [emp][!0-9]
- C. cat emp[x-z]
- D. cat emp[a-z]
Explanation
In a shell glob, `[!0-9]` matches one character that is not a digit, so `cat emp[!0-9]` selects names beginning with `emp` and having a non-digit next character. To allow any additional characters, a trailing `*` would also be needed.
