Linux Foundation Certified System Administrator (LFCS) — Question 117

What is the output of the following command?
for token in a b c; do
echo -n ${token};
done

Answer options

• A. anbncn
• B. abc
• C. $token$token$token
• D. {a}{b}{c}
• E. a b c

Correct answer: B

Explanation

The command iterates over the tokens 'a', 'b', and 'c', outputting each token without a newline due to the '-n' option in 'echo'. This results in the concatenated string 'abc', making option B the correct answer. The other options either misrepresent the output format or include unnecessary characters.
