The following scripts were added: - try.sh: a fun use of the program. - pootify.sh: a local pootifier that downloads a web page (or use a local file) and either changes it to text or writes html which can be viewed in a local browser. - pootify.cgi.sh: a CGI version that the judges added but made to use bash(1) and pass shellcheck(1). There is an issue that is known with this and the 'Historical remarks' discusses this in more detail as well as how to use the pootify.sh and pootify.cgi.sh scripts. The README.md file has been formatted as well.

# Script to download a page and pootify it. You can pipe it through less(1) to
|
|
# see the output or you can redirect it to a file and open it in your local
|
|
# browser (use the -r option for that).
|
|
#
|
|
# Note from 2023: this used to be a CGI script that used lynx(1) which has
|
|
# security features but lynx does not work with redirects, it would appear, and
|
|
# unfortunately links(1) does not have such restrictions. If you wanted to use
|
|
# it anyway you could change the -dump to -source and see how it goes. It might
|
|
# also be that if it was used as a CGI script it would work well but this has
|
|
# not been tested.
|
|
#
|
|
# Example uses:
|
|
#
|
|
# ./pootify.sh URL=https://microsoft.com | less
|
|
#
|
|
# ./pootify.sh -r URL=https://microsoft.com > ms.html
|
|
#
|
|
# and then open ms.html in your local browser. Neither are as nice as a rendered
|
|
# html page as a script from another page and certainly it's less convenient but
|
|
# you can at least enjoy the output somewhat, the latter one more so, perhaps.
