Documenting commands # or $ before sudo?
Documenting commands # or $ before sudo?
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?
You're viewing a single thread.
Edit: looks like this is wrong lol, that's what I get for not verifying. So maybe $ does make more sense!
Original message:
I think I'd go with #.
The non-root user probably doesn't have permission to run the sudo command as www-data user, but root does.
Unless you previously set permissions for the non-root user to sudo as www-data.

You are wrong. E. g. in Debian (and Ubuntu) the default
sudoersfile contains%sudo ALL=(ALL:ALL) ALLthat means that any user in the
sudogroup is permitted to execute any command as any other user. The same for redhat/fedora, but the group name iswheelthere.lol thanks for the correction
