There are three special # lines that alter the behavior: a line consisting of just "--" causes # the next line to be echoed verbatim to the output. A line # containing just "%%" causes all the remaining filenames (wildcards # allowed) in the rest of the file to be ignored. A line containing # just "!!" exits the script when reached (unless preceded by a line # containing just "--"). #Author: Richard L.
