Issues with features in echo $variable and paste from clipboard.

It says cannot execute binary file. Me $variable on echo stops working on occasion in fact more often than not even with the variable stored it returns a blank line. Also my paste function has started to only work on occasion how can I fix these issues ? The only experience I had is worked out my self from sources an trial an error so please keep in mind I’m still an early learner. Although I have a high iq ( I know someone with a iq over 110 : mines well over that I just usually assume anyone with moderate intelligence these days can code. I’ve literally not had access to the internet most of my life ) ( high iq often low eq, low eq normally leads to social issues, combine this with my issues with authority and ego and it leads to a miss spent youth. Well when you also add extreme bullying an other issues to someone already struggling to resolve eq sentiments effectively leads to recurring incarceration in my experience lol )
