To compare folders I recommend you use rsync

rsync -n -avxl src/ tgt/

This will show you how src differers from tgt
Is this what you are looking for?

hi,
hope can help you some.

<filelist.sh> to list all the files under given directory

Code:

cd $1
for i in *
do
	echo $i
done

below will generate three section, only in first dir, only second dir, in both dir

Code:

sh filelist.sh dir1 > dir1file
sh filelist.sh dir2 > dir2file
echo "Those in dir1 but not dir2:"`comm -23 dir1file dir2file`
echo "Those in dir2 but not dir1:"`comm -13 dir1file dir2file`
echo "Those in both dir1 and dir2:"`comm -12 dir1file dir2file`
rm dir1file dir2file

Atleast on Solaris, you can do this:

Code:

$ dircmp -s folder1 folder2 |grep -v "^ *$" |grep -v Page
./file3

Thanks for your answers, but i want work with variables and not directly with the file.

With rsync as comm if i give $var instead the directory directly, i have errors...

What are you talking about? You posted example folder1, folder2 so the answers were provided accordingly. What is stopping you from putting the commands in a script, say "compare.sh":

Code:

#!/usr/bin/ksh
f1=$1
f2=$2
dircmp -s $f1 $f2 |grep -v "^ *$" |grep -v Page

Then you can simply pass the arguments to the script:

Code:

ksh compare.sh folder1 folder2

Or I'm completely missing something?
