Which command and options are used to rename a Linux user, move their home directory, and update the comment?

• A. usermod -l bnew bcassini -m -c "Brenda Palmer" -d /home/bpalmer
• B. usermod -r bcassini -l bpalmer -m -c "Brenda Palmer" -d /home/bpalmer
• C. usermod -l bpalmer bcassini -m -c "Brenda Palmer" -d /home/bpalmer
• D. usermod -L bpalmer bcassini -m -c "Brenda Palmer" -d /home/bpalmer

Answer: (C)

This uses the usermod command to change several attributes of an existing user in one go: the login name, the home directory, and the comment field. The -l option sets the new login name, so bcassini becomes bpalmer. The account to modify is the existing one listed after the options, bcassini. The -d option specifies the new home directory path as /home/bpalmer, and the -m option moves the current home directory contents into that new location so the user’s files follow the account name. The -c option updates the GECOS field, which stores the user’s full name or a comment, to "Brenda Palmer." Putting these together achieves renaming, relocating the home directory, and updating the display name in a single command. Other options either rename to a different name, use an invalid flag, or would lock the account, which doesn’t accomplish the requested tasks.
