CS2121 lab exercise 1 part a1 - hint

You just need to create a file, called "1.regexp", that contains a single line, which just contains an apostrophe character, like this:

egrep will pick out any lines that contain characters that match the pattern, so in this case, it will pick out any lines containing an apostrophe, which is what the question asks for.

You do not want any other characters in the file, except the end-of-line.

You especially do not want any extra space or tab characters, and you must not have more than one line!
