The "echo" command takes whatever text follows it on the command line and displays it on stdout. It does not execute that text.
Please remember that permitting an arbitrary
string to be executed as a command is not something to do casually. When done in the wrong place at the wrong time, it can be used as a security exploit.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
