Which command creates a new Linux user with a comment field?

• A. useradd -c "Paul Denunzio" pdenunzio
• B. adduser pdenunzio
• C. useradd pdenunzio -c "Paul Denunzio"
• D. createuser pdenunzio

Answer: (A)

Setting the descriptive field for a new Linux user is done with the -c option on the useradd command, which fills the GECOS (comment) field in the password database. The correct command uses useradd with -c "Paul Denunzio" followed by the username, creating the account and storing the full name as the comment. Other options either use a different command that may not set the GECOS field, or place the -c flag after the username (which isn’t reliable across systems).
