Command last truncates usernames larger than 8 characters. When try to use the parameter -w (wide) it reports that it is an invalid option:

#last -w
last: invalid option -- w
Usage: last [-num | -n num] [-f file] [-t YYYYMMDDHHMMSS] [-R] [-x] [-o] [username..] [tty..]

Why do the last command truncate usernames that contains more than 8 characters in RHEL 5?
