I have a list of files that should be in a dir tree and want to remove

else rm it)... any quick way to do this?
Perhaps something like this will help:
find /dir -type f | \
grep -v `cat excludelist` | \
xargs rm
Regards,
Note quite since it will see every file after the first as a file to be
grepped instead of filtered out... I was playing with the idea of doing
a tcsh foreach loop on each file and then using it cut down the output
of find... the problem there is it is O(n^2) where is a "good" solution
is O(n) [I need to do this {don't ask the reasons} everytime I build a
program I am developing]
