You didnt mention what you wanted to use the first two chars for but if you are using Korn shell then you could use one of the builtins (which should run faster than the cut command) and set a variable equal to the first two chars. For example:
${parameter%%pattern} which deletes the longest suffix that matches the pattern. You can modify this construct to set a variable to the shortest suffix of the parameter by removing one of the percent signs: ${parameter%pattern}. Finally, you can play the same game with prefixes by using the pound sign: ${parameter##pattern} or ${parameter#pattern}
