Sheesh...you're working pretty hard to get these two characters in
there...
Your best bet is to write a small C program to do the job:
main(...)
{
fd = open(...);
lseek(fd, 0, SEEK_END);
write(fd, ";;\n", 3);
}
That, obviously, has not been compiled or tested :-}, nor is there
any error-checking. It will beat the pants off the "scroll to the
end and type ';;'" process, though.
There may even be Perl or Pythonic ways of doing the same thing.
Look for "seek" or "append" methods in these scripting languages. In
essence, you want to seek to the end of the file, write the two
characters there, and close the file.
If you have a number of files to deal with, just put those operations
in a loop.
