kill

 
Sends a signal to a process, usually related to stopping the process. All signals except for SIGKILL and SIGSTOP can be intercepted by the process to perform a clean exit. More information: https://manned.org/kill.
 
  • Terminate a program using the default SIGTERM (terminate) signal:
     
    kill {{process_id}}
     
  • List available signal names (to be used without the SIG prefix):
     
    kill -l
     
  • Terminate a background job:
     
    kill %{{job_id}}
     
  • Terminate a program using the SIGHUP (hang up) signal. Many daemons will reload instead of terminating:
     
    kill -{{1|HUP}} {{process_id}}
     
  • Terminate a program using the SIGINT (interrupt) signal. This is typically initiated by the user pressing Ctrl + C:
     
    kill -{{2|INT}} {{process_id}}
     
  • Signal the operating system to immediately terminate a program (which gets no chance to capture the signal):
     
    kill -{{9|KILL}} {{process_id}}
     
  • Signal the operating system to pause a program until a SIGCONT ("continue") signal is received:
     
    kill -{{17|STOP}} {{process_id}}
     
  • Send a SIGUSR1 signal to all processes with the given GID (group id):
     
    kill -{{SIGUSR1}} -{{group_id}}
