Exam 101-500 Topic 3 Question 289 Discussion

Actual exam question for Lpi's 101-500 exam
Question #: 289
Topic #: 3
Which of the following commands prints a list of usernames (first column) and their primary group (fourth column) from the /etc/passwd file?

Suggested Answer: C Vote an answer

The cut command is used to extract selected fields from each line of a file. The -d option specifies the delimiter that separates the fields, and the -f option specifies the fields to print. The /etc/passwd file contains information about the users on the system, and each field is separated by a colon (:). Therefore, cut -d : -f 1,4
/etc/passwd will print the first and fourth fields of each line, which are the username and the primary group ID respectively. The other commands are either invalid or do not perform the desired task. The fmt command is used to reformat paragraphs of text, but it does not have a -f option. The split command is used to split a file into smaller files, but it does not have a -c option. The paste command is used to merge lines of files, but it does not have a -f option. References:
