webchk is a command-line tool developed in Python 3 for checking the HTTP status codes and response headers of URLs. It accepts one or more URLs as arguments. Furthermore, a sitemap URL can be passed using the -p option to download its content, extract the URLs and check their statuses.

webchk is available on PyPI and can be installed using pip with the following command:

$ pip install webchk

Webchk does not require any 3rd party packages to run. So it can also be cloned from GitHub and run as a module:

$ git clone https://github.com/amgedr/webchk.git
$ cd webchk
$ python3 -m webchk

webchk [-h] [-i INPUT] [-o OUTPUT] [-p] [-a] [-l] [-s] [-f] [-v]
             [urls [urls ...]]

positional arguments:
  urls

optional arguments:
  -h, --help                   show this help message and exit
  -i INPUT, --input INPUT      Read input from a file
  -o OUTPUT, --output OUTPUT   Save output to a file
  -p, --parse                  Follow links listed in .xml URLs
  -l, --list                   Print URLs without checking them
  -v, --version                Print the version number

Check a list of URLs from a file (one URL per line):

$ webchk -i urls.txt

Check the status of a sitemap file and all the URLs listed in it:

$ webchk -p http://example.com/sitemap.xml

List the URLs in a file without checking their HTTP status:

$ webchk -li urls.txt

Check the URLs in a file and .xml files in it:

$ webchk -pi urls.txt

List the URLs in a file and .xml files in it:

$ webchk -pli urls.txt

List the URLs in a sitemap without checking their status:

$ webchk -lp http://example.com/sitemap.xml
