Do you mean something like:

if [ -z "$CLASSPATH" ]; then
  for jar in /usr/share/lib/*.jar; do
  # do nothing, or something very minimal

Yep, it's a possibility, but a bit kludgey.

Maybe there could be two files, ~/.cp_add and ~/.cp_remove. Each
contains regexps of files to add to and remove from the classpath,

So if I don't want anything, I put in my ~/.cp_remove:


To only remove jaxp, I'd put:


And if I have a directory of jars I frequently use (~/jars), I could put this in
my ~/.cp_add:


Not sure how this could be implemented in /bin/sh though.
