python catch kill signal
#We can check for Ctrl-C with KeyboardInterrupt exception as follows:
while True:
print "Echo ", raw_input(">")
except KeyboardInterrupt:
print "Good bye"
#When python process was killed, we will not get KeyboardInterrupt. But we can instead catch SIGTERM sent by kill command.
#In order to catch SIGTERM, we can do:
import signal
import sys
def signal_term_handler(signal, frame):
print 'got SIGTERM'
signal.signal(signal.SIGTERM, signal_term_handler)
#List of signal is available in POSIX Signals. Note that SIGKILL cannot be caught.
