This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.



















  • You need to search for shell quoting, this has been asked before. Note also you're trying to use nested single quotes, which won't work as expected (they can't be nested, so you end up with two quoted strings with text inbetween).
