The command that prints a list of usernames (first column) and their primary group (fourth column) from the /etc/passwd file is:
C. `cut -d : -f 1,4 /etc/passwd`
In this command:
- `cut` is used to select specific columns.
- `-d :` specifies the delimiter as a colon since the /etc/passwd file uses colons to separate fields.
- `-f 1,4` specifies that we want to extract the first (username) and fourth (primary group) fields.
This command will extract and display the desired information from the /etc/passwd file.
