kill

问题 I'm looking for the best, or any way really to start a process from php in the background so I can kill it later in the script. Right now, I'm using: shell_exec($Command); The problem with this is it waits for the program to close. I want something that will have the same effect as nohup when I execute the shell command. This will allow me to run the process in the background, so that later in the script it can be closed. I need to close it because this script will run on a regular basis and

Is it possible to stop a query without killing mysql itself? 回答1: mysql>show processlist; mysql> kill "number from first col"; 回答2: Just to add KILL QUERY **Id** where Id is connection id from

问题 The child process is started with subprocess.Popen(arg) Is there a way to ensure it is killed when parent terminates abnormally? I need this to work both on Windows and Linux. I am aware of this solution for Linux. Edit: the requirement of starting a child process with subprocess.Popen(arg) can be relaxed, if a solution exists using a different method of starting a process. 回答1: Heh, I was just researching this myself yesterday! Assuming you can't alter the child program: On Linux, prctl(PR

问题 I'm setting : - (void)applicationWillTerminate:(UIApplication *)application { [UIApplication sharedApplication].applicationIconBadgeNumber = 1; } in my application delegate but the badge is never updated...

问题 I need to run a process, wait a few hours, kill it, and start it again. Is there an easy way that I can accomplish this with Python or Bash?

The sleep just waits an hour, then the kill shuts down that process. The while loop just keeps doing it
