Catching a signal for a program

Are there any ways to catch a signal for a program where you don't have access to source code of the program. Is having a signal handler the only way?

trap command traps the signals and other events.

  • Format: trap command signal_list
  • Example: Clean txt files from /tmp whenever signals(2,15)
# vim my_script.sh
    trap "{ /usr/bin/rm -r "/tmp/*.txt" }" SIGINT SIGTERM ERR EXIT
