How can I remove the current process/application which is already assigned to a port?
For example: localhost:8080
This question is related to
windows
cmd
localhost
port
command-prompt
One line solution using GitBash:
tskill `netstat -ano | grep LISTENING | findstr :8080 | sed -r 's/(\s+[^\s]+){4}(.*)/\1/'`
Replace 8080 with the port your server is listening to.
If you need to use it often, try adding to your ~/.bashrc
the function:
function killport() {
tskill `netstat -ano | findstr LISTENING | findstr :$1 | sed -r 's/^(\s+[^\s]+){4}(\d*)$/\1/'`
}
and simply run
killport 8080
Result for Windows Command Prompt
In my case, 8080 is the port I want to kill
And 18264 is the PID listening on port 8080
So the task you have to kill is the PID for that particular port
C:\Users\Niroshan>netstat -ano|findstr "PID :8080"
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 18264
taskkill /PID 18264 /f
If you're using Windows Terminal then the killing process might be little less tedious.
I've been using windows terminal and kill PID
works fine for me to kill processes on the port as the new Windows Terminal supports certain bash commands. For example: kill 13300
So, the complete process will look like this-
netstat -ano | findstr :PORT
kill PID
For Example:
PS C:\Users\username> netstat -ano | findstr :4445
TCP 0.0.0.0:4445 0.0.0.0:0 LISTENING 7368
TCP [::]:4445 [::]:0 LISTENING 7368
PS C:\Users\username> kill 7368
PS C:\Users\username> netstat -ano | findstr :4445
PS C:\Users\username>
See when I typed the first command to list processes on the port it returned empty. That means all processes are killed now.
Update: kill
is an alias for Stop-Process. Thanks, @FSCKur for letting us know.
Step 1 (same is in accepted answer written by KavinduWije):
netstat -ano | findstr :yourPortNumber
Change in Step 2 to:
tskill typeyourPIDhere
Note: taskkill
is not working in some git bash terminal
Here is a script to do it in WSL2
PIDS=$(cmd.exe /c netstat -ano | cmd.exe /c findstr :$1 | awk '{print $5}')
for pid in $PIDS
do
cmd.exe /c taskkill /PID $pid /F
done
If you can use PowerShell on Windows you just need :
Get-Process -Id (Get-NetTCPConnection -LocalPort "8080").OwningProcess | Stop-Process
I know that is really old question, but found pretty easy to remember, fast command to kill app that are using port.
Requirements: [email protected]^ version
npx kill-port 8080

netstat -ano | findstr :PORT
kill PI
I was running zookeeper on Windows and wasn't able to stop ZooKeeper running at 2181 port using zookeeper-stop.sh, so tried this double slash "//" method to taskkill. It worked
1. netstat -ano | findstr :2181
TCP 0.0.0.0:2181 0.0.0.0:0 LISTENING 8876
TCP [::]:2181 [::]:0 LISTENING 8876
2.taskkill //PID 8876 //F
SUCCESS: The process with PID 8876 has been terminated.
With Windows 10 default tools:
Open Windows PowerShell as Administrator
Find PID (ProcessID) for port 8080:
netstat -aon | findstr 8080
TCP 0.0.0.0:8080 0.0.0.0:0 LISTEN 77777
Kill the zombie process:
taskkill /f /pid 77777
where "77777" is your PID
For use in command line:
for /f "tokens=5" %a in ('netstat -aon ^| find ":8080" ^| find "LISTENING"') do taskkill /f /pid %a
For use in bat-file:
for /f "tokens=5" %%a in ('netstat -aon ^| find ":8080" ^| find "LISTENING"') do taskkill /f /pid %%a
For Windows users, you can use the CurrPorts tool to kill ports under usage easily:
If you are using GitBash
Step one:
netstat -ano | findstr :8080
Step two:
taskkill /PID typeyourPIDhere /F
(/F
forcefully terminates the process)
You can do by run a bat file:
@ECHO OFF
FOR /F "tokens=5" %%T IN ('netstat -a -n -o ^| findstr "9797" ') DO (
SET /A ProcessId=%%T) &GOTO SkipLine
:SkipLine
echo ProcessId to kill = %ProcessId%
taskkill /f /pid %ProcessId%
PAUSE
the first step
netstat -vanp tcp | grep 8888
example
tcp4 0 0 127.0.0.1.8888 *.* LISTEN 131072 131072 76061 0
tcp46 0 0 *.8888 *.* LISTEN 131072 131072 50523 0
the second step: find your PIDs and kill them
in my case
sudo kill -9 76061 50523
If you already know the port number, it will probably suffice to send a software termination signal to the process (SIGTERM):
kill $(lsof -t -i :PORT_NUMBER)
We can avoid this by simple restarting IIS, using the below command:
IISRESET
In case you want to do it using Python: check Is it possible in python to kill process that is listening on specific port, for example 8080?
The answer from Smunk works nicely. I repeat his code here:
from psutil import process_iter
from signal import SIGTERM # or SIGKILL
for proc in process_iter():
for conns in proc.connections(kind='inet'):
if conns.laddr.port == 8080:
proc.send_signal(SIGTERM) # or SIGKILL
continue
In Windows PowerShell version 1 or later to stop a process on port 3000 type:
Stop-Process (,(netstat -ano | findstr :3000).split() | foreach {$[$.length-1]}) -Force
As suggested by @morganpdx here`s a more PowerShell-ish, better version:
Stop-Process -Id (Get-NetTCPConnection -LocalPort 3000).OwningProcess -Force
