# # control-alt-delete - emergency keypress handling
# #
# # This task is run whenever the Control-Alt-Delete key combination is
# # pressed. Usually used to shut down the machine.
#

# ps -ef | grep -i tty UID PID PPID C STIME TTY TIME CMD root 1933 1 0 12:15 tty2 00:00:00 /sbin/mingetty tty2 root 2163 2162 12 12:15 tty3 00:26:23 /usr/bin/Xorg :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-72V2K6/database -nolisten tcp root 3907 3037 0 15:53 pts/1 00:00:00 grep -i tty
