ps -efl | grep PORT_NUMBER | kill -9 process_found_previously
how to complete the last column?
如何完成最后一栏？
回答by Shawn Chin
The problem with ps -efl | grep PORT_NUMBERis that PORT_NUMBERmay match other columns in the output of psas well (date, time, pid, ...). A potential killing spree if run by root!
问题ps -efl | grep PORT_NUMBER在于它PORT_NUMBER也可能匹配输出中的其他列ps（日期、时间、pid 等）。如果由 root 运行，潜在的杀戮狂潮！
I would do this instead :
我会这样做：
PORT_NUMBER=1234
lsof -i tcp:${PORT_NUMBER} | awk 'NR!=1 {print }' | xargs kill
Breakdown of command
命令分解
- (
lsof -i tcp:${PORT_NUMBER}) -- list all processes that is listening on that tcp port - (
awk 'NR!=1 {print $2}') -- ignore first line, print second column of each line - (
xargs kill) -- pass on the results as an argument tokill. There may be several.
- (
lsof -i tcp:${PORT_NUMBER}) -- 列出在该 tcp 端口上侦听的所有进程 - (
awk 'NR!=1 {print $2}') -- 忽略第一行，打印每行的第二列 - (
xargs kill) - 将结果作为参数传递给kill. 可能有几个。

Propose to use fuser command:
建议使用 fuser 命令：
fuser -k -TERM -n tcp ${PORT_NUMBER}
回答by DanS
kill $( lsof -i:6000 -t )
Or if you need permissions:
或者，如果您需要权限：
sudo kill $( sudo lsof -i:6000 -t )

sudo fuser -k 8080/tcp

This syntax is probably much more recent than the date of the question!
此语法可能比问题的日期更新得多！

... | awk '{ print }' | xargs kill -9
please test with "echo" instead of "kill" before running
请在运行前使用“echo”而不是“kill”进行测试
回答by Shams Naved
To kill all processes listening on a particular port, e.g. port 8864
杀死侦听特定端口的所有进程，例如端口 8864
kill -9 $ \`lsof -i:8864 -t\`
Replace 8864 by the port you want.
将 8864 替换为您想要的端口。
