From your description, I am not sure about if this long string is the one to cut out or if there is anything inside it to be removed, or if it is always the same, nor do I see how your file looks like so to locate the unwanted stuff.

Also the combination of many cat, cut, egrep, awk and sed are things you could most probably do with 1 of them instead of all 5 commands.

Hint:
Show an input example line and the expected output, thanks.
