Is terminal code not…code?

N-no?

Its a program/command called mount that takes in command line arguments. The program is documented (in overwhelming detail) in the manual which is accessible online or using the program man (man mount)

The reason someone would recommened that command over the GUI is its universally installed on all Linux machines. OP said they were using Linux Mint. There are several Linux Mint distributions with different Desktop Managers (MATE/Cinnamon/Xfce) that all have different workflows of mounting an ISO file. mount is universal.

Commands are normally not considered “code” on their own. Someone who just runs commands on their computer to get a few operations done will normally not learn any programming constructs or concepts. If you’re doing shell scripting that usually crosses the line into code as you’d be using if statements, for loops, etc, which you normally don’t use if you’re just moving files around or whatever in the shell.

This is just invoking a command, it’s basically the same as double-clicking a .exe in Windows, just without a mouse. There’s no need to “learn coding” to do this. Coding involves complex logic; this doesn’t.

The biggest put off to Linux is the absolute shit community it has

Have you ever given it a shot? Most Linux users I’ve encountered are very friendly. Yes, there are some boards (like Arch forums) where people get pissy at noobs; however Arch isn’t a noob-friendly distro, in contrast to Mint/openSUSE etc.

Attitude matters as well; if you start off by shitting on stuff you have limited knowledge of, you won’t get a friendly response.
