Shell Programming and Scripting

Using Sol 10 + KSH.

I need to run a find command on the whole system "/" and exclude a bunch of explicit directories and files that may or may not be on each system.

I cannot use the -name because i dont want to exclude all dirs named just specific paths.
-path/-wholename is not an option on the Solaris FIND utility

What i have is working, but I just wanted to throw this out there and have someone else look at it to make sure I am not overlooking something and/or solicit better alternatives.

Code:

EXCLUDE=`$(ls -bdi /path/to/dir1 /path/to/dir2 /var/dir3/dir4 | sed -e 's/ *\([0-9][0-9]*\) .*/-inum \1 -o/')
find / \( $inode_matches -nouser -o -nogroup \) -prune -o -type f -print

Why not grep -v?

hmm i could pipe find/ through grep.

Ill try both and see which is faster
