# bun-self

Let's say you have a file called `script.ts` with the following content:

```ts

import { $ } from "bun";

await $`curl -s wttr.in`;

```

And you really want your friend to run it, so you decide to share a gist with them, but they are not as cool as you and don't have Bun installed yet. A problem.

But you won't even believe what happens next:

```sh

bunx bun-self script.ts

```

And you send this beauty to your friend instead (`script.run.ts`):

```ts

#!/usr/bin/env bash

/*/.this-doesnt-exist 2>/dev/null

## Please do not edit this part of the script, this is a loader created by "bunx bun-self"

if ! [ -x "$(command -v bun)" ]; then

    echo "Installing bun.sh"

    sleep 2

    curl -fsSL https://bun.sh/install | bash

    echo "Now let's run the script"

    echo ""

fi

bun $0

exit 0

#*/

// Script starts here

import { $ } from "bun";

await $`curl -s wttr.in`;

```

Your friend just has to run it either with

```sh

bash script.run.ts

```

or

```sh

chmod +x ./script.run.ts

./script.run.ts

```

They won't even know what hit them.

Of course it doesn't have to be a friend, you can hide that stuff in plain sight at your job with an innocent-looking "bash script.run.ts" in the "scripts" section of your package.json and no one even will notice that they are now happy Bun users.
