       If you want to kill a process by its name instead of its PID number,
       which is easier if you have to kill processes from the same binary,
       here are the commands depending of your operating system:
       
       
       **FreeBSD / Linux**
       
           $ killall pid_name
       
       
       **OpenBSD**
       
           $ pkill pid_name
       
       
       **Solaris**
       
       Be careful with Solaris killall. With no argument, the command will
       send a signal to every active process, which is not something you
       want.
       
           $ killall pid_name
