Shell Programming and Scripting

Hi,

Can you tell me how to compare two directories and write the differing files to some other folder?

Use diff recursively and redirect the output to a file.

thats correct, but i want to copy the whole differing files not the names only.

Is it possible?

It would help if you stated precisely what you are trying to accomplish by at least creating two directories with a two or three simple files and then ls output of the desired result.

How do you expect to accomodate two differing files with the same name in the same destination folder? Do you require a specific renaming scheme? If a file exists in one directory but not the other, should it be copied or not? Should subdirectories be visited as well?

If you have any other special requirements, please state them now before people waste time on unhelpful suggestions.

try this one, hope it works for you

Code:

 
diff <dir1> <dir2>| xargs -I FNAME  echo FNAME>> tmp_file

for filepath in `cat tmp_file`
do
     dir_name=`echo $filepath|cut -d" " -f3|cut -d":" -f1`
     file_name=`echo $filepath|cut -d" " -f4`
     cp $dir_name/$file_name <target_dir> 2>>error_log
done

/bin/rm -f tmp_file

Use absolute path for directory listing.

Thank you all.
