Lynne, thanks for the info...your script produces what I need, except
that my arguments are not on separate lines. However, I have managed to
write the following script that allows "Program\_Files" to be passed as
'Program Files' to find. Especially important was the eval ($call)
(also thanks to Cameron). This seems to have removed the problem that
find was having. I also think that using the \_ is better than the
question mark and I can replace it with a space in the loop. Here is
what I ended up with:
#!/bin/sh
paths_to_exclude='/mnt/dosc/windows /mnt/dosc/quickenw
/mnt/dosc/Program\_Files /mnt/dosc/rom_zips'
call="find /mnt/dosc/"
for i in $paths_to_exclude ; do
i=$(echo $i | sed 's/\\_/ /g')
call="$call -path '$i' -prune -o"
done
call="$call -print"
echo $call
eval "$call"
Thanks for everyone's help in steering this to a conclusion.

Kirk,
Try something like the following - this works for me. The set -x
provides a
"trace" and should be removed for actual use.
#!/bin/sh
set -x
paths_to_exclude='/tmp/dir1/Program Files
/tmp/fileobJEbT-rep-tarfh
/tmp/orbit*
/tmp/quickenw'
call=`echo "$paths_to_exclude" | ( stuff=
while read line
do
stuff="$stuff -path '$line' -prune -o"
done
echo $stuff)`
call="find /tmp/ $call"
call="$call -print"
echo "Calling..."
echo $call
eval $call
