Shell Programming and Scripting

Hi all,

I need to compare the contents of 2 directories where the file contents are similar and take out the filenames whose contents does not exist within the 2 directories.

Directory1

1
2
3
4

Directory2

54
55
56
57

Does anyone has a script which can do this?
At the end of the command, all the files that does not exist when comparing the 2 directories should be cp -p to another new directory.

Thanks.

Hi!
you can use sdiff with the option -s to print only not identical lines.

ls -la /first_dir > 1.dir
ls -la /seconed_dir >2.dir
sdiff -s 1.dir 2.dir

I hope this help.
regards joerg

Hi Joerg,

Thanks for your advice, but the filenames are totally different, however the content is the same, in this case, how would i go about doing it?

There are 800+ files in one directory and 500+ in one directory, i know for sure that about 200+ do not share the same contents and i want to move them to another directory.

Is the timestamp of the file in side the first directory the same as in the second directory.
Please give us a output of the ls -la command for both directorys.
Which kind of contense it is?

Hi Joerg,

No the only thing that is the same is the xml file contents, i need to compare the file contents in one directory with the other directory. Do you know of a script which can do that?

Loop thru files in source directory; see if file exists in destination; if it does then see if the contents differ...

Code:

#!/usr/bin/ksh

SOURCE=/path/to/source/dir
DEST=/path/to/dest/dir
cd $SOURCE
for i in *
do
    if [ -f $DEST/$i ]
    then
        echo file $i exists
        if cmp -s $i $DEST/$i
        then
            echo files are the same
        else
            echo files are different
        fi
    else
        echo file $i does not exist
    fi
done

Thanks for your help, i appreciate it but if the filenames which are different are over 200+ files, how do i automate this with diff to search through their contents in different directories?
