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 disagree completely.
The bad practice is running commands directly as root. It’s fine if you prefer for your own environment but sudo is the best practice.
Additionally, which distro doesn’t have sudo? I’m sure there are some but by far the majority of distos have and use sudo.
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.
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.
