能把除了无法直接确认的TTY输入记录进程都直接杀死：

[gwz@rl5 ~]$ tty
/dev/pts/9
[gwz@rl5 ~]$ wzappkey -p assh
Killed: Memory Snooper uid=0 pid=4425 command=/usr/bin/Xorg :0 -br -audit 0 -auth /v r/gdm/:0.Xauth -nolisten tcp vt8 D▒▒▒s▒
Found you have 9 login sessions running, if this is correct,
press <Enter> to continue; otherwise, please cancel it now:

Please enter password for assh:
Warning: pid=29082 is using your tty!
