You must have very long user names there. That is not typical.
What I would do in that case would be to find the tty of the user and
then use ps to determine a process id of a process associated with
the tty then use the /proc pseudo-directory to list the name.
who
...see uid example 1003 on pts/1 with process id example 5770...
ls -l /proc/5770
...read the user name from the ls long listing output...
I did not actually try that. None of the machines that I have access
to have login names longer than eight characters. So I don't know if
that would actually work. But I think it would because the kernel
provides the /proc system as a pseudo filesystem and ls can list long
names from there.
