CompTIA Linux+ Powered by LPI (LX0-103) — Question 15

Which of the following commands prints a list of usernames (first column) and their primary group (fourth column) from the /etc/passwd file?

Answer options

• A. fmt -f 1,4 /etc/passwd
• B. split -c 1,4 /etc/passwd
• C. cut -d : -f 1,4 /etc/passwd
• D. paste -f 1,4 /etc/passwd

Correct answer: C

Explanation

The correct command is 'cut -d : -f 1,4 /etc/passwd', which uses the colon as a delimiter to extract the first and fourth fields from the /etc/passwd file. The other options either use incorrect commands or incorrect syntax for extracting the desired fields, thus they will not yield the intended output.
