import { execFileSync } from "node:child_process";
execFileSync(file: string): Buffer 
      The child_process.execFileSync() method is generally identical to execFile with the exception that the method will not
return until the child process has fully closed. When a timeout has been
encountered and killSignal is sent, the method won't return until the process
has completely exited.
If the child process intercepts and handles the SIGTERM signal and
does not exit, the parent process will still wait until the child process has
exited.
If the process times out or has a non-zero exit code, this method will throw an Error that will include the full result of the underlying spawnSync.
If the shell option is enabled, do not pass unsanitized user input to this
function. Any input containing shell metacharacters may be used to trigger
arbitrary command execution.
