diff file size

[haeman]

I have two directory that want to find their difference , I use the command "diff" could find the difference when the file is not exist , now if I want to also check the size of the file , that mean if tthe size is not the same , then report the error , what can i do ? thx

$ls dir1
-rwxrwxrwx 1 root root 10 Sep 9 11:02 file1

$ls dir2
-rwxrwxrwx 1 root root 20 Sep 9 11:02 file1

Hi,

What about:
find dir1 -type f | sort | while read FILE
do
SIZE=`ls -l $FILE | awk '{print $5}'`
echo $FILE#$SIZE
done > dir1.lst

find dir2 -type f | sort | while read FILE
do
SIZE=`ls -l $FILE | awk '{print $5}'`
echo $FILE#$SIZE
done > dir2.lst

sdiff -s dir1.lst dir2.lst
