A simple bash script to check if a URL is valid or not.
You don't have to install anything, this is just a plain bash script. However you are able to get it using git clone:
foo@bar:~$ git clone [email protected]:herczogzoltan/url-checker.gitThe script echoes the error message and the url checked into the standard output. Also when an error occurs, it saves the URL into a file called invalid_urls.txt.
