A fast, async link checker

Finds broken URLs and mail addresses inside Markdown, HTML, `reStructuredText`, websites and more!

Usage: lychee [OPTIONS] <inputs>...

Arguments:
  <inputs>...
          The inputs (where to get links to check from). These can be: files (e.g. `README.md`), file globs (e.g. `"~/git/*/README.md"`), remote URLs (e.g. `https://example.com/README.md`) or standard input (`-`). NOTE: Use `--` to separate inputs from options that allow multiple arguments

Options:
  -c, --config <CONFIG_FILE>
          Configuration file to use
          
          [default: ./lychee.toml]

  -v, --verbose...
          Set verbosity level; more output per occurrence (e.g. `-v` or `-vv`)

  -q, --quiet...
          Less output per occurrence (e.g. `-q` or `-qq`)

  -n, --no-progress
          Do not show progress bar.
          This is recommended for non-interactive shells (e.g. for continuous integration)

          [default: 1d]

          Don't perform any link checking. Instead, dump all the links extracted from inputs that would be checked
