如何在NodeJS中通过child_process运行“>”UNIX命令？

Question

I'm trying to run a command on a Linux based OS and save the output on a file. This is what I do when i'm using terminal:

wpa_passphrase SSID sample_password > /etc/wpa_supplicant.conf

I want to run this command on my NodsJS app but it doesn't work properly:

const wpa_passphrase = spawnSync('wpa_passphrase', [`"${ssid}"`, `"${password}"`, '>', paths.wpaConfig]);

The problem is, it doesn't run the > command in order to save the output on my specified path. how should I run this command by spawnSync ?
