Documenting commands # or $ before sudo? (feditown.com)

This might be a stupid question, but hear me out.
I regularly document steps to install various software for myself on my wiki
More recently, I managed to use different custom text in the source markdown to prepend # and $ automatically, so commands can be copied more easily while still clarifying if it should be run as a normal user or as root.

Run command as user

$ some cool command

Run command as root/superuser with sudo

# some dangerous command

I usually remove and sudo and use the # prefix. However, in some cases, the sudo actually does something different that needs to be highlighted. For example, I might use it to execute a command as the user www-data

sudo -u www-data cp /var/www/html/html1 /var/www/html/html2

I often use $ as a prefix, but # would also make sense.
How would you prefix that line?

Bad practice is not using sudo (I do use it), but assuming that everyone has sudo installed and configured the same way as you have.

Additionally, which distro doesn’t have sudo? I’m sure there are some but by far the majority of distos have and use sudo.

Almost all distros have sudo. But many of them don't install it by default. Most popular distros except Ubuntu (I mean Debian, Fedora and RHEL clones) provide a choice to user at install time: set the root password or install sudo and enable it for the admin user. In OpenSUSE sudo is installed by default, however it is configured in slightly different way than usually. Etc., etc.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
