There are several ways to kill a range of consecutive processes in Linux. Here are a few methods:

  1. Using pkill with a range of process IDs: If you know the process IDs (PIDs) of the processes you want to kill, you can use the pkill command with a range of PIDs to terminate them. For example, to kill processes with PIDs from 1000 to 2000, you can run the following command: pkill -P 999 --signal SIGTERM This command sends the SIGTERM signal to all processes whose parent process ID is within the range of 1000 to 2000.
  2. Using the kill and xargs commands: You can also use the combination of kill and xargs commands to kill a range of consecutive processes. First, you need to list all the process IDs you want to kill. Then, pipe the output to xargs to execute the kill command for each PID. For example: echo {1000..2000} | xargs kill This command sends the default SIGTERM signal to all processes with PIDs from 1000 to 2000.
  3. Using a loop and the kill command: Another way is to use a loop in a shell script to iterate through the range of process IDs and send the kill command for each PID. Here's an example using a Bash script: #!/bin/bash start_pid=1000 end_pid=2000 for ((pid=start_pid; pid<=end_pid; pid++)); do kill $pid done Save this script to a file (e.g., kill_range.sh), make it executable (chmod +x kill_range.sh), and run it.


Remember, killing processes should be done with caution, as terminating certain processes abruptly may result in system instability or loss of data. Use these methods responsibly and only terminate processes you are sure should be terminated.
