I can integrate programs made in html and css3 in python for example, using a framework ...
Is it possible to make a box for the html to run inside the shell script?

Hi jeffecarneiro and welcome to LQ.

Not that I'm aware of. I'm moving this thread to the Programming forum in case there's a viewer there who may know different.

Not sure if I understand the question, but are you asking about things like these?

Welcome to LQ and the programming forum!

I do not really understand the question.

It would be helpful if you could describe in more detail what you are trying to do. Please see the Site FAQ for guidance in asking a more complete question so that others will be better able to help.

I think that the OP is asking if they can run HTML from within a shell script.

Actually I think it is possible to access an HTML page, or cause the browser to run and load a certain page as part of a shell script, but it will not be exactly as they seemed to have said, which would be a window within the terminal that contains this. I'm not sure if that actual behavior is a mandatory need, or if once they can run a browser and load an HTML page that they will be all set.

Meanwhile, what would be important to know is whether or not a graphical desktop environment is currently running. If your Linux is only running at the command line and no graphical desktop is loaded, this problem becomes far worse to consider tackling.

great! the flask will answer me thank you!

Welcome to LQ!!! You seem to have a great interest, but need more on:
basic concepts, and tech writing.
I don't understand how web programming (flask etc) helps toward shell programming.
To me, shell is an interface to OS syscalls, but web is more of GUI 'apps'.

I did see your next Thread; I'd recommend 2 different directions:
OS concepts and python.
Think about how .py could be both a CLI and produce web code.

Going advanced, 3 'hot' areas: security, cloud, web design/code (think: Equifax Struts)

Can you clarify more about this "html in bash"? Clarify so one could picture your vision.

A web-search of: [allintitle:] run html in bash
Found:https://au.answers.yahoo.com/questio...1102052AAjDMcA
But note that that was confusing too.

Best wishes; continue ...!!! Hope to hear more details from you.
