I am working on scripts to manage user accounts a little easier. In the User Manager GUI app there is a field 'Full Name'. However, the CLI command 'useradd' does not have a field for 'Full Name'. It does have a 'comment' field (The new user's password file comment field) as shown in 'man useradd'. Question, are these two the same field and if not, where is the 'Full Name' data stored by User Manager and what exactly is the comment field of the 'useradd' command?
