When I use the
uptime command on OS X, this error is printed:
$ uptime uptime: /dev/ttys003: No such file or directory 20:57 up 36 days, 22:10, 3 users, load averages: 1.77 1.37 1.75
By running the
who command, I see that there is another terminal logged in -- but I don't have any other terminals or SSH sessions.
$ who Kevin console Mar 10 17:49 Kevin ttys000 Mar 14 17:45 kevin ttys003 Mar 14 20:59
