find -ls field separator

Hi all,

I am using AIX 5.2 and 5.3
and have to do data migration from old machine to new machine.

After migration, I have to do verification.

There is a very quick and dirty verification
is to ensure the filesize is the same after the migration.

The method is very simple:
find MyDirectory -type f -ls | awk '{print $11, $7}'

To produce a report in both the old and new machine
and then use the join command to
let the filename (i.e. $11) as key
and then compare the 2 filesize values (i.e. $7)

This work for 99.9%
except when the filename contain SPACE or SPACES.

My question is:
Can the find -ls
command use TAB or other non-space character
as the field separator ?

If not, any idea to solve this problem ?

Hmmmmm, the filename-with-space is really a headache to me
for many many times
but I have no choice !

Thanks in advance.

I don't know, but you can of course change your awk program.
For example:

find MyDirectory -type f -ls | \
awk '{s=$7;sub(/^([^[:space:]]*[[:space:]]*){10}/,"");print $0,s}'

nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.

find MyDirectory -type f -printf "%p %s\n"
