8n 16n 32n
struct passwd {
        char    *pw_name;               /* user name */
        char    *pw_passwd;             /* user password */
        uid_t   pw_uid;                 /* user id */
        gid_t   pw_gid;                 /* group id */
        char    *pw_gecos;              /* real name */
        char    *pw_dir;                /* home directory */
        char    *pw_shell;              /* shell program */
