Kill -2 or Kill -INT ,how does it kill process

it fixes the issue Kill -2 sends an interrupt (2 is the value associated with SIGINT). This will wake up the sleep call but then the loop continues. If you send a 15 (SIGTERM), the process should terminate.

If I kill a System.Diagnostics.Process with .Kill(), do I also need to call .Close()?


By : 戴東華

I think the issue was by ths following , System.Diagnostics.Process implements IDisposable via the Component class, and the protected Dispose(bool) method calls Close(). It is generally considered good practice to dispose of disposable resources when you are done with them, as this will immediately release any resources associated with the class (not having to wait for the GC to run).
So to answer your question:
code :
using(Process proc = CreateProcess())
{
    StartProcess(proc);
    if (!proc.WaitForExit(timeout))
    {
        proc.Kill();
    }
}

how to kill a passthru process upon the kill of a php script?


By : Mustafa Temur
Date : March 29 2020, 07:55 AM
seems to work fine Function passthru() spawns a shell to run your command and then blocks until the passthru process returns. Those are independent processes with different Process IDs than the php interpreter running your script. You can kill the script but you won't kill the processes it started.
However the spawned processes have the same Process Group ID (PGID) and you can use that to kill them or sent them any other signal. The PGID in our case would be the same as the Process ID (PID) of the php script.
code :
PPID   PID  PGID   SID TTY      TPGID STAT   UID   TIME COMMAND
24077 12484 12484 24077 pts/9    12484 S+    1000   0:00  |   \_ php sleepScript.php
12484 12486 12484 24077 pts/9    12484 S+    1000   0:00  |       \_ sh -c sleep 500
12486 12487 12484 24077 pts/9    12484 S+    1000   0:00  |           \_ sleep 500
kill -15 -24077
