w utility reports who's logged on, what processes they're running, etc.
Why does it print two non-ascii characters, apparently as the (nonexistent) args for bash?
In iTerm2 they render as white question marks on a black background.
Piped to a file and viewed with vi, I see:
15:41 up 5 days, 1:46, 11 users, load averages: 1.67 1.69 1.47 USER TTY FROM LOGIN@ IDLE WHAT me console - Fri13 5days - me s000 - Fri14 28:15 -bash ÿ¿ /bin/bash me s001 - Fri15 3:21 -bash ÿ¿ /bin/bash
When ssh'd into the mac from a Windows PuTTY 0.74 shell, they render as ▒▒ .
The man page for
w suggests that it might print a hyphen, but doesn't even hint at Unicode.
