Lychee

Install Lychee, then:

lychee --base 'https://github.com/explodinglabs/superstack/wiki/' .

Doesn’t work with Github Wiki links, unless you include the .md extension.

npm install -g markdown-link-check

.mlc.json

{
  "ignorePatterns": [{ "pattern": "^http" }, { "pattern": "^mailto:" }],
  "replacementPatterns": [{ "pattern": "^\\./", "replacement": "" }]
}

find . -name '*.md' -print0 | xargs -0 -n1 markdown-link-check -q --config .mlc.json
