no error checking but first thoughts:
Code:
oldifs=$IFS
IFS='
'
find /home/chris/tmp/usr/test |
while read f
do
    dest=$(echo $f | sed 's/usr/var/')
    [ -d "$f" ] && mkdir -p "$dest" || ln "$f" "$dest"
done
IFS=$oldifs

this produced:
Code:
find /home/chris/tmp/usr
/home/chris/tmp/usr
/home/chris/tmp/usr/test
/home/chris/tmp/usr/test/oracle
/home/chris/tmp/usr/test/oracle/script 1
/home/chris/tmp/usr/test/oracle/script 2
/home/chris/tmp/usr/test/db2
/home/chris/tmp/usr/test/db2/script 1
/home/chris/tmp/usr/test/db2/script 2

find /home/chris/tmp/var
/home/chris/tmp/var

bash linker.sh
find /home/chris/tmp/var
/home/chris/tmp/var
/home/chris/tmp/var/test
/home/chris/tmp/var/test/oracle
/home/chris/tmp/var/test/oracle/script 1
/home/chris/tmp/var/test/oracle/script 2
/home/chris/tmp/var/test/db2
/home/chris/tmp/var/test/db2/script 1
/home/chris/tmp/var/test/db2/script 2

and if you run ls -lRi on both dirs you should see that the files are linked, not copied.

The example below verifies the change of the previous example: example% cachefslog /home/sam /var/tmp/samlog: /home/sam Example 4: Halting the logging of a directory.
