## MD-LINK-CHECKER - Utility to check url, section reference, and path links in Markdown files
[![PyPi](https://img.shields.io/pypi/v/md-link-checker)](https://pypi.org/project/md-link-checker/)

This is a simple command line utility to check url, section reference, and path
links in Markdown files. It iterates through the specified Markdown files and
checks each link in the file for validity. If no file is specified then it
defaults to checking `README.md` in the current directory. URL fetches can be
slow over the internet so they are checked simultaneously (maximum 10 in
parallel per file by default but you can change that using the
`-p/--parallel-url-checks` option). There are a number of similar utilities
available so why did I create another one? Well, all those that I tried didn't
work!

E.g. check links in the `README.md` file in the current directory:

```
$ cd /path/to/my/project
$ md-link-checker
```

Check links in all the `README.md` files across your projects:

```
$ cd ..
$ md-link-checker */README.md
```
