How to Kill A Process In Bash?

6 minutes read

To kill a process in Bash, you can use the kill command followed by the process ID (PID) of the process you want to terminate. Here's how to do it:

  1. First, you need to identify the PID of the process you want to kill. To do this, you can use the ps command to list all running processes along with their PIDs. The ps aux command is commonly used for this purpose.
  2. Once you have identified the PID of the process you want to kill, you can use the kill command. The basic syntax of the kill command is as follows: kill [options] Replace with the actual process ID you obtained earlier.
  3. By default, the kill command sends the SIGTERM signal (termination signal) to the process, which allows the process to perform any necessary cleanup tasks before terminating. The process should gracefully exit after receiving the SIGTERM signal. If the process does not respond to SIGTERM or if you want to forcefully terminate it, you can send the SIGKILL signal using the -9 option. For example: kill -9
  4. After executing the kill command, the specified process should be terminated, and its resources will be released. You can verify if the process has been killed by re-checking the list of running processes using the ps command or tools like pgrep and pkill.


Remember, killing a process can have consequences, so it's recommended to use caution and consider any potential impacts before forcibly terminating a process.

What is the command to kill a process group in Bash?

The command to kill a process group in Bash is kill -- -$PGID, where $PGID is the process group ID.

What is the command to kill a process silently in Bash?

The command to kill a process silently in Bash is kill -9 <PID>, where <PID> is the process ID of the process you want to kill. The -9 option is used to send the SIGKILL signal to the process, forcing it to terminate immediately without giving it a chance to clean up. This is considered a "silent" way of killing a process because it abruptly terminates it.


How to terminate a process by its executable path in Bash?

You can terminate a process by its executable path in Bash using the pkill command. Here's an example:

  1. Open the Terminal.
  2. Find the process you want to terminate by running the pgrep command with the name or path of the executable: pgrep -f /path/to/executable This will return the process ID (PID) of the matching process.
  3. Terminate the process using the pkill command with the -9 option: pkill -9 -f /path/to/executable Replace /path/to/executable with the actual path to the executable. The -9 option sends a SIGKILL signal to forcefully terminate the process. Note that using -9 can cause potential data loss or corruption, so use it with caution.


That's it! The process should now be terminated.
