# Self-Host Blog Images in Two Lines of Bash

My blog is a folder of markdown files.

Everybody hates broken links, so here's how I download files to put in `/dist`:

```bash
# Download all images referenced by URL.
wget $(grep -RIhEo 'https?://[^ )]+' . | grep -e png -e jpg -e jpeg)
```

```bash
# Replace all markdown links with relative file names at root.
# e.g. [test](/123.png) <- [test](https://example.com/123.png)
sed -i '.bak' -E 's#\(https?:/.*/([^/]+\.(png|jpg|jpeg)).*\)#(/\1)#g' *.md
```
