function execSync
Usage in Deno
```typescript import { execSync } from "node:node__child_process.d.ts"; ```
execSync(command: string): Buffer
The `child_process.execSync()` method is generally identical to [exec](../.././node__child_process.d.ts/~/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 `SIGTERM` signal 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](../.././node__child_process.d.ts/~/spawnSync).
**Never pass unsanitized user input to this function. Any input containing shell**
**metacharacters may be used to trigger arbitrary command execution.**
