## Handle OS Signals

[API Reference](https://doc.deno.land/https/raw.githubusercontent.com/denoland/deno/master/cli/js/lib.deno.unstable.d.ts#Deno.signal)
|
|
|
|
You can use `Deno.signal()` function for handling OS signals.
|
|
|
|
```ts
|
|
for await (const _ of Deno.signal(Deno.Signal.SIGINT)) {
|
|
console.log("interrupted!");
|
|
}
|
|
```
|
|
|
|
`Deno.signal()` also works as a promise.
|
|
|
|
```ts
|
|
await Deno.signal(Deno.Signal.SIGINT);
|
|
console.log("interrupted!");
|
|
```
|
|
|
|
If you want to stop watching the signal, you can use `dispose()` method of the
|
|
signal object.
|
|
|
|
```ts
|
|
const sig = Deno.signal(Deno.Signal.SIGINT);
|
|
setTimeout(() => {
|
|
sig.dispose();
|
|
}, 5000);
|
|
|
|
for await (const _ of sig) {
|
|
console.log("interrupted");
|
|
}
|
|
```
|
|
|
|
The above for-await loop exits after 5 seconds when sig.dispose() is called.
