Check if your website links are broken with LinkChecker

LinkChecker

Okay let’s make it quick. If you are looking for:

• a command line tool
• check and search for broken links on (most probably your) website
• don’t want to install anything except docker

Okay then I have something for you: LinkChecker (GitHub).

docker run --rm -it -u $(id -u):$(id -g) ghcr.io/linkchecker/linkchecker:latest --no-status -o text -v https://example.com

• --no-status removes some python print outs regarding number of running threads
• -v verbose otherwise working links are not printed
• -o text is the default option but I want to highlight that there is more. html for example which is pretty handy as report dropping out from a pipeline. Or dot which was new to me and plays together with graphviz which can draw graphs.

Might be interesting for you:

• --check-extern Self explanatory is it? Without this option it does not request anything else than the given hostname.
• --no-warning To concentrate on errors.

Many more possibilities can be found in the command line reference. But should this article should be enough to give you a jump start.
