My God Linux can be opened with any wrong command it breaks, unlike windows which keeps everything closed.

One aspect of Linux that helps to make it a very secure Desktop operating system, is that system changes require “root permission”. A virus cannot infect your Linux computer unless a user supplies the necessary credentials (password) for it to install.
Always be cautious when using “sudo” and don’t use it unless necessary. “sudo” (super user do) allows system changes (root access), which could damage the operating system if used inappropriately, so always ensure that you know “why” you are using sudo before you use it.

Clearing thumbnails from your account does NOT require root access, so “sudo” should NOT be used. The correct command is:
rm -rf ~/.cache/thumbnails/*
“sudo” IS required when changes to the operating system, so things like installing software and updating the operating system will usually require use of “sudo” and/or entering your password.
