The child_process.execSync() method is generally identical to exec 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 SIGTERMsignal and doesn't exit, the parent process will wait until the child process
has exited.
If the process times out or has a non-zero exit code, this method will throw.
The Error object will contain the entire result from spawnSync.
Never pass unsanitized user input to this function. Any input containing shellmetacharacters may be used to trigger arbitrary command execution.
