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.

Okay. I have my config files set up to add /sbin and /usr/sbin to my PATH -- that's probably a config that dates back at least a decade -- but it looks like Debian defaults to not having /usr/sbin or /sbin in PATH for non-root users; you can see this in /etc/profile, where it's only adding /usr/local/sbin, /usr/sbin, and /sbin to root's PATH, but not to other users.
If you run
su -l, then that'll give you a login shell as root, and that'll have those in the path.You can also add them to a regular user's path. I don't know what the "right way" to modify PATH for a graphical desktop is these days, so I can't give much help there; with xdm starting Xorg, which is what I do, it's to put it in a ~/.xession file, something like:
and for login bash shells, like for if you ssh into the system or log in on the console, in ~/.bash_profile, the same.
But GNOME under Wayland and all those new desktop environments probably have some way to modify PATH, something which they run at when you log in, and I don't know the appropriate place to stick those or which you use.
