[Discuss] cygwin problem

[Noel Burton-Krahn]

There are a couple of traps here:

  for FIL in `find -iname '$DOC_TYPE'`; do

1. the single-quotes around '$DOC_TYPE' will prevent it from expanding

2. this causes bash to buffer the whole output of find, then split it.
 The pipe below will work for huge directory listings

I'd try this instead:

  find "$DIR" -iname "$DOC_TYPE" | while read FIL; do
