Copy colorful terminal (emulator) text output and paste as HTML?

I want to write notes (in HTML format) when learning Linux. When I need to note colorful terminal text output, I want the color of terminal text can be remained in my notes, e.g.:

Note 1: Test

The output of xx command is

<pre>
[root@webserver ~]# ll /
total 100
drwxrwxrwt.   7 root root  4096 8月  24 12:22 <span style='background-color:green; color:blue;'>tmp</span>
drwxr-xr-x.  14 root root  4096 7月  19 21:20 <span style='color:blue;'>usr</span>
</pre>

I can manually add HTML code wrapper around the plain text, but I hope there's an automatic way to achieve that.

Currently, I'm using putty on Windows to connect to remote CentOS linux server.

Solution 1:

Use the script utility to capture the terminal output to a file (ansi color control characters included) and then convert it to html with ansi2html script. Eg:

inigo:tmp> script
Script started, file is typescript
inigo:tmp> ls
#
# lots of colour output
# 
inigo:tmp> exit
exit
Script done, file is typescript
inigo:tmp> cat typescript  | ansi2html.sh > typescript.html

If using PuTTY, "All session output" login option will also keep the ansi color codes.

As an alternative to ansi2html, you could use aha - Ansi HTML Adapter.

Solution 2:

After seven years and nine months, putty still don't support 'Copy as HTML' feature.

I had already turned to Fedora linux as my primary operating system for work for about six years and nine months because of end-of-life of Windows XP.

Now, gnome-terminal v3.x had added 'Copy as HTML' feature for 3 years (git commit GNOME bug report), and it works as what I expected, so I will use gnome-terminal to do this job if I needed. See the screenshots below.
