demo of "set -f" in bash

glob_test.sh

#!/bin/bash
# run this in a dir with some .zip files

# note that we do NOT escape glob patterns here
opts="-iname *.zip"

# normally, bash will expand *.zip and find will complain about arguments
echo "find will complain:"
find $opts
echo "========================================"

# prevent bash from expanding glob
set -f

echo "find works!" 
# this works
find $opts
echo "========================================"

# back to original globbing behavior for remainder of script...
set +f
