Shell Programming and Scripting

FILE_BASE="${i}" | awk -F: '{print $2}' doesn't make sense. This is what you need:
FILE_BASE=$(print "${i}" | nawk -F: '{print $2}')
Also, I am confused by FILE_BASE=${i##*:${HOME_DIR}/}. Where id HOME_DIR come from?

I can't accout for the zeros unless your find command is outputing additional fields.

tmarikle,
Thank you once again. I got it going, but with the other commands that you gave me.
Do you think me not having nawk functionality and due to which I am using awk, it might be the issue with your initial script?

I use nawk, which is a newer awk than the earlier awks, because my Solaris system's awk is mostly useless to me. Your system's awk may actually be nawk anyway.

...and yes, it could have contributed to the problems that you experienced if it's not there.

This is an intriguing problem, and a common one at that. Basically we want to know if two files differ by size with the same names in two directories (or if files exist in one directory but not the other). So in essence we have a compound key = filename+filesize. This is a perfect job for uniq as long as we can build a good key.

So we generate two outfiles with the filenames and sizes. Take a long ls, discard the first line (total) and awk the 5th (size) and last (filename) columns:

ls -l $DirA | awk '{print $NF, $5}' | tail +2 > /tmp/ls.a
ls -l $DirB | awk '{print $NF, $5}' | tail +2 > /tmp/ls.b

Then we sort and count the number of "key" lines, then filter those which are unique:

sort ls.a ls.b | uniq -c | awk '($1 == 1)'
1 bad.jpg 384
1 fred.jpg 19580
1 fred.jpg 384

So this spits out files that only exist on one side or files that aren't the same size. By grepping these in both tmp files we learn which is A versus B side.

Make sure you remove the tmp files when you're done.

P.S.: For two boxes that don't share a drive mount, use SSH and $PWD if the paths are the same. If not, there's a bit more trickery involved.

You can run the following script to print the file name and size.
Assuming your directories contain the same number of files and same file names.

script name = 1.sh
----------------------
\rm -rf _out1 2>/dev/null
for f in `ls -1 | sort`
do
if [ "$f"xx = "_out"xx -o "$f"xx = "1.sh"xx ]
then
continue
fi
# executables have * at the end
f=`echo $f | cut -d'*' -f1`
#directories have "/" at the end of the file name
f=`echo $f | cut -d'/' -f1`
ls -s $f | awk -F" " '{ print $NF " " $1 }' >>_out1
done
You can run this script in 2 directories and redirect the ouput to 2 different files , say _out1 and _out2..
then use "paste _out1 _out2 " this gives you sorted list with file names and sizes.

Hope this helps.
