function execFileSync
Usage in Deno
```typescript import { execFileSync } from "node:node__child_process.d.ts"; ```
execFileSync(file: string): Buffer
The `child_process.execFileSync()` method is generally identical to [execFile](../.././node__child_process.d.ts/~/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](../.././node__child_process.d.ts/~/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.**
