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.

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?

I dislike when documentations add sudo because what if I am root already or what if sudo is not installed on my machine and I cannot just copy and paste the lines because I have to avoid pasting sudo.

Also fyi ArchWiki also uses the # approach.

Can't you just select the text without the sudo prefix..?

Sometimes the commands contain pipes or &&, which is a minor nitpick, but I still prefer # over sudo in documentation.
