try on your machine

The command watchexec is a tool used to automatically run commands whenever changes are detected in files within a directory.

In the given command, watchexec is being used with the following options:

--restart: This option tells watchexec to restart the command whenever a change is detected.
--signal ${SIGKILL}: This option specifies the signal to be sent to the command when restarting. ${SIGKILL} is a placeholder for the signal used to kill a process immediately, which is represented by the value 9 in the operating system.
${my_server}: This is a placeholder for the command that you want to run and restart using watchexec. It should be replaced with the actual command you want to execute.

So, the overall command will execute ${my_server} and monitor the directory for any changes. Whenever a change is detected, it will restart ${my_server} using the SIGKILL signal.
