How to convert Linux's shell output to HTML?

Is there any easy way to convert bash output to HTML? For example, if I have some colorized output in bash (something like htop), how can I convert it to HTML, with corresponding stylings/tags/css/etc.

As suggested in @eli's answer, you can use script to capture the colored output to a file.

You can then convert the output to HTML with aha, the "Ansi HTML Adapter", which should be available in your distribution's repositories: apt install aha or yum install aha for Debian-based or Redhat-based distributions.

If you want to capture only a single command, use the -c option:

script -c "grep --color ..."

This will save the output to a file named typescript in your current directory.

To save to a different file, add the file name at the end:

script -c "grep --color ..." my_grep_colored_output

See man script for other options.

To capture several commands from an interactive session, just start script without a command, and enter Ctrl-d to exit script when done.

To just view the file in color, use less -R.

To convert it to HTML with aha :

aha -s -f typescript > output.html

or 

aha -s < typescript > output.html

The -s option makes it write a style sheet in the html header instead of using inline styles through the file. That makes it easier to change colors if some background/foreground combinations turn out hard to read in a browser.

1.) check that ansifilter and script programs are installed

2.) script -c 'ansible-playbook -i /tmp/or/some /tmp/other/command.yml' -O /tmp/myTypescriptOutput.file

(script writes the output of a command to a file in typescript notation)

3.) convert to html, e.g. to view with your browser:

ansifilter -i /tmp/myTypescriptOutput.file -H -o output.html

convert to rtf, e.g. to view with libreoffice or word

ansifilter -i /tmp/myTypescriptOutput.file -R -o output.rtf

see man ansifilter for other options (latex, tex, svg, pangot, txt, ...)


(additional, if highlight is installed:

highlight /tmp/myTypescriptOutput.file --force

... this will print the saved-shell output in color, like if it was executed at first time)

There's ansifilter plus some tools like highlight will produce colorized html from plain text such as source files.

Both available here.

Without any pretty-printing, the simplest thing you can always do is to escape everything that needs escaping, and wrap a basic HTML shell around (the following should be valid minimal HTML5). For example, get a hold of fastesc: http://raa.ruby-lang.org/project/fastesc/, and that wrap it into an HTML shell.

If you want to preserve the ANSI magic, then you need to convert that to HTML, perhaps with http://ansi-sys.rubyforge.org/

And then do something like this, depending on your needs:

require 'ansisys'


def ansi_escape(string)
    terminal = AnsiSys::Terminal.new
    terminal.echo(string)
    terminal.render 
end

def to_html(string)
    %Q{ <!DOCTYPE html>
        <title>Converted to html</title>
        <pre>
        #{ansi_escape(string)}
        </pre>
    } 
end

Yes, you need to pipe the result through a tool like ansi2html.
