how to kill multiple cargo instances

If ps -ef | grep cargo shows four instances of Cargo running, you can kill them by following these steps:

Identify the process IDs (PIDs): The output of ps -ef | grep cargo should show you the process IDs (PIDs) of the four instances of Cargo running on your system. These PIDs are typically located in the second column of the output.

Kill the processes: Once you have identified the PIDs of the Cargo processes, you can use the kill command to terminate them. For example, you can run kill PID for each of the four PIDs to terminate the corresponding Cargo processes. Alternatively, you can use the pkill command to kill all processes that match a certain pattern. For example, you can run pkill cargo to kill all Cargo processes running on your system.

Verify that the processes are terminated: After killing the Cargo processes, you can use ps -ef | grep cargo again to verify that they are no longer running on your system. If there are no more Cargo processes running, you should see no output from the grep command.

Note that killing running processes can have unintended consequences and may result in data loss or system instability. Make sure to save any unsaved work and backup any important data before proceeding with the above steps.
