kill process on port code example

Example 1: kill process on port

#To list any process listening to the port 8080:
lsof -i:8080

#To kill any process listening to the port 8080:
kill $(lsof -t -i:8080)

#or more violently:
kill -9 $(lsof -t -i:8080)

Example 2: cmd kill process on port

## check and kill used "ports"
netstat -ano | findstr :8080
taskkill /PID <yourid> /F

Example 3: windows kill port

Example 4: kill process on port

# To list any process listening to the port 8080:
lsof -i:8080

# To kill any process listening to the port 8080:
kill $(lsof -t -i:8080)

# or more violently:
kill -9 $(lsof -t -i:8080)
# (-9 corresponds to the SIGKILL - terminate immediately/hard kill signal: see List of Kill Signals and What is the purpose of the -9 option in the kill command?. If no signal is specified to kill, the TERM signal a.k.a. -15 or soft kill is sent, which sometimes isn't enough to kill a process.).

#list process running on specified port (here 80, change to your port)
sudo lsof -i:80

#kill process on specified port (here 80, change to your port)
sudo kill $(sudo lsof -t -i:80)

Example 6: kill process on port

lsof -i:3000           // Change 3000 to whatever your port is!
sudo kill 9 <PID>      // Change <PID> to the Pid number the above command returns
