As it is, any line longer than 159 characters will just overflow.
You need to use substr() not awk to shorten a line. Even after that
modification, that won't solve your actual problem as the awk script
will just shorten EACH line (when record separator is newline), not
the whole output.
There are ports which seems to do what you want to do.
