## FAQ

[More here.](https://github.com/rdwz/capture-website#faq)

### How can I capture websites from a file with URLs?

Lets say you have a file named `urls.txt` with:

```sh
https://sindresorhus.com
https://github.com
```

You can run this:

```sh
filename='urls.txt'

while read url; do
  capture-website "$url" --output "screenshot-$(echo "$url" | sed -e 's/[^A-Za-z0-9._-]//g').png"
done < "$filename"
```
