如何终止匹配超过 30 分钟的 grep 的进程?
我有一组并行运行的进程.
I have a set of processes that run in parallel.
偶尔有些人会比脚本允许的时间更长:
Occasionally some hang around longer than the script is supposed to allow:
$time_start = microtime(true)
$max_run_time = 30 * 60; // 30 minutes, measured in seconds
while ((microtime(true)-$time_start) < $max_run_time) {
// do stuff, but quit after 30 minutes
}
我想终止该脚本中运行时间超过 30 分钟的旧进程.
I'd like to kill old processes of this script that have been around longer than 30 minutes.
如何从命令行执行尽可能多的操作?
How can I do as much from the command line?
以下是当前正在运行的进程示例:
Here's a sample of current running processes:
> ps aux | grep script.php

my_user 31542 28.4 1.1 704476 393152 ? S 07:02 170:02 php /path/to/my/script.php
我可以使用 `pkill -f "php/path/to/my/script.php" 将它们全部杀死
I can kill them all using `pkill -f "php /path/to/my/script.php"
但是我怎么能杀死旧的呢?
But how can I just kill the old ones?
推荐答案
要获取运行时间超过 30 分钟的名为 PROCESS_NAME 的进程列表可以发出以下awk命令:
To obtain the list of processes named PROCESS_NAME which are running longer than 30 minutes you
can issue the following awkcommand:
ps ax -ocmd,pid,etime | awk '/PROCESS_NAME/{split($(NF),a,":");if(a[1]>30)print}'
只获取运行的pid
ps ax -ocmd,pid,etime | awk '/PROCESS_NAME/{split($(NF),a,":");if(a[1]>30)print $(NF-1)}'
您可以将其通过管道传递给 xargs kill，如下所示:
You can pipe this to xargs kill, like this:
ps ax -ocmd,pid,etime | awk '/PROCESS_NAME/{split($(NF),a,":");if(a[1]>30)print $(NF-1)}'
| xargs kill
