Proste polecenie do zabicia procesu po zajmowany porcie

Totalna pierdoła ale, again, może się komuś przydać:

kill_by_port

#!/bin/bash

# Check if port is provided
if [ -z "$1" ]; then
  echo "Usage: $0 "
  exit 1
fi

PORT=$1

# Find the process ID (PID) using the port
PID=$(lsof -t -i:$PORT)

# Check if a process is using the port
if [ -z "$PID" ]; then
  echo "No process found using port $PORT"
  exit 0
fi

echo "Process using port $PORT found: PID $PID"

# Attempt to gracefully terminate the process using SIGQUIT
kill -3 $PID
echo "Sent SIGQUIT to process $PID. Waiting for termination..."

# Wait a moment to give the process time to terminate
sleep 2

# Check if the process is still running
if ps -p $PID > /dev/null; then
  echo "Process $PID did not terminate. Sending SIGKILL..."
  kill -9 $PID
  echo "Process $PID killed."
else
  echo "Process $PID terminated successfully."
fi
