使用awk有条件地杀死进程 [英] Conditionally killing a process using awk

问题描述

嗨伙计们，



我正在尝试结合几个awk命令而我没有运气。如果在一段时间内没有一定量的下载流量，那么这个想法就是杀死一个进程。



任何帮助都会受到赞赏。



我尝试了什么：



我可以得到以下信息来正确查找正在运行的qbittorrent进程的PID：

Hi folks,

I'm trying to combine a couple of awk commands and I'm having no luck. The idea is to kill a process if there has been less that a certain amount of download traffic within a certain period of time.

Any help would be appreciated.

What I have tried:

I can get the following to properly find the PID of a running qbittorrent process:

echo $( ps aux | grep "[q]bittorrent" | awk '{ print $2 }' )

以下将告诉我过去几秒内是否有低下载活动：

And the following will tell me if there has been low download activity over the last few seconds:

collectl -c1 -i5 -sn | awk 'NF==4 && $2<200  { print $1 }'

输出是过去5秒内下载的KB数量。



现在我要结合这些 - 在第二个命令中用kill替换 print $ 1 ，然后输出第一个命令。



我尝试了几种变体，例如

The output is the amount of KB downloaded in last 5 seconds.

Now I want to combine these - replacing the print $1 in the second command with "kill" followed by the output of the first command.

I've tried several variations, such as

sudo $( collectl -c1 -i5 -sn | awk 'NF==4 && $2<20 { print "kill " $( ps aux | grep "[q]bittorrent" | awk '{ print $2 }' ) }' )

但无济于事。

推荐答案

（ps aux | grep[q] bittorrent| awk'{print

( ps aux | grep "[q]bittorrent" | awk '{ print

2}'）

以下将告诉我过去几秒内是否有低下载活动：

And the following will tell me if there has been low download activity over the last few seconds:

collectl -c1 -i5 -sn | awk 'NF==4 &&

2< 200 {print

2<200 { print
