The command that will generate a list of user names from '/etc/passwd' along with their login shell is 'cut -d: -f1,7 /etc/passwd'. Option D is the correct answer. The 'cut' command is used to extract specific fields or columns from a file. The '-d' option specifies the delimiter, and the '-f' option specifies the fields to extract. In this case, the command will extract the first ('1') and seventh ('7') fields from '/etc/passwd', using a colon (':') as the delimiter. The '/etc/passwd' file contains a list of user accounts on the system, with each line representing a single user. The fields are separated by colons, the first field is the user name and the seventh field is the login shell. Therefore, the command will generate a list of user names from '/etc/passwd' along with their login shell.
