Today I was quite perplexed, as I could not unmount a drive in Ubuntu. The message was that I needed to be root to do it. No problem, you can either log in to your root user account (discouraged for security reasons), or you can use sudo.

Sudo is essentially a command for doing something with elevated privileges. Let’s say you want to move a file, but you can’t because only the admin can. In this case, you can type the same command for moving the file, but with typing “sudo” in front, you can perform that action as a root user.

So my problem was that try as I might I could not find the command to unmount. Mount was fine, it’s simply “mount”, but try as I may nothing worked. I found a bas command list in the end, and it turns out that the command for unmounting a drive is “umount”. I don’t know why the “n” needed to be omitted, but at least I found it.

If you need a long list of commands you can use, take a look at these bash commands, you will find some useful stuff in there. I am finally realizing why the terminal is a good idea!
