I want to search some text for a user provided string. I was getting input and escaping it with qr(). I then used the qr()'ed value as input to my grep. However, I realized that qr() works too well for my pursposes. I want the user input to be interpretted as a string literal, not as a RegEx, ie if the user inputs "[ab]", I want to search for "\[ab\]" - that exact sequence of characters. How do I go about searching for a string literal in a bigger block of text?
