internal Commands of bash - that are commands hardcoded from within bash
- do have a short documentation via help, eg. "help test". Every
command, that is not bash internal should have it's own manual page -
"man bash", "man du"... The manual pages use to bear more information,
so I prefer to use "man bash" even for the internal commands.

"set -x" makes the shell write every line that is executed to stderr, so
you can trace the execution of Your script. It is the same as if You
call "sh -x script-name".

Try to use less instead. It's eg. on the german gnuwin mirror
ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin32/porters/Hirmke_Michael/less-321-win32-bin.tar.gz
.... And don't forget to read the README :-). Maybe this needs ncurses
too...

Another way is to make a function that emulates the more command:
function more() {
  case "$1" in
  ""|"-") /WINNT/system32/more.com ;;
  *)      /WINNT/system32/more.com < "$@" ;;
  esac
}
