问题描述
我有一个使用端口TCP 16969的应用程序.有时它需要快速快速重启软件内核.但是，如果我启动得太快，那么就会被Exception in thread "main" java.net.BindException: Address already in use锁定.
I have one application which use port TCP 16969. It requires sometimes a quick software kernel reboot on the fly. But if i launch it too fast, then i am locked with Exception in thread "main" java.net.BindException: Address already in use.
所以没有任何借口，我想触发我的BASH脚本，该脚本可以用16969杀死正在运行或监听的任何端口.但是我该怎么做呢?
So without any excuse i want to trigger my BASH script which can kill any running or listening port with 16969. But how can i do that?
$ lsof -w -n -i tcp:16969 # this gives me a list of 50 lines but how can i tell apply kill to all on this port?
推荐答案
我认为:
lsof -i tcp:22 | grep LISTEN | awk '{print $2}' | xargs kill
应该做到这一点.
要在松散之前仔细检查它想运行什么命令，请在kill之前添加一个echo，如下所示:
To double check what commands it wants to run before letting it loose add an echo before the kill like this:
lsof -i tcp:22 | grep LISTEN | awk '{print $2}' | xargs echo kill
然后它将列出通常会杀死的PID
It'll then list the PIDs that it would ordinarily kill
