How to close the nohup command in Linux after running it?

After running the command with nohup, you can close it in several ways:

1. Pressing Ctrl+C will terminate the terminal session in which the nohup command is running, also stopping the execution of the nohup command.
2. Terminate the running of the nohup command using the kill command. First, find the process ID (PID) of the nohup command using the ps command: ps aux | grep nohup. Then, use the kill command with the PID as a parameter to terminate the running of the nohup command: kill PID.
3. If specifying an output file when running the nohup command, you can terminate the nohup command by deleting the output file. Use the command rm to delete the output file: rm file name.

Please be aware that terminating the running of the nohup command in any way will result in the nohup command process being terminated without receiving any termination signals. Therefore, it is recommended to ensure that the nohup command has completed its task before terminating it.
