On cygwin 1.5.25, this prints "None". By default, cygwin has neither a 'root' nor a 'tty' group, so cygwin punts and chooses the only group name that is guaranteed to exist on underlying Windows. Meanwhile, wall is installed with the permissions of the user who ran the cygwin installer: $ ls -lF /usr/bin/wall $(tty) - -rwxrwxrwx+ 1 eblake Users 8192 Apr 1 01:55 /usr/bin/wall.exe* crw-rw-rw- 1 eblake None 136, 0 Nov 30 2006 /dev/tty0 $ id uid=1007(eblake) gid=513(None) 513(None),544(Administrators),545(Users) There is no /usr/bin/write on cygwin, and I've never tried using wall to see whether terminal messaging is even reasonable to expect to work. It may just be that worrying about 'who -a' on cygwin is not worth the effort, since I'm not sure whether terminal messaging is supported. - -- Don't work too hard, make some time for fun as well!
