Delete duplicates via script?
Hello,
i have the following problem:
there are two folders with a lot of files.
Example:
FolderA contains AAA, BBB, CCC
FolderB contains DDD, EEE, AAA

How can i via script identify AAA as duplicate in Folder B and delete it there? So that only DDD and EEE remain, in Folder B?

Thank you in advance for looking into this.

No two files with same name can be in the same folder.

when i enter "diff" at the command line, it is recognized as command. I am using ubuntu, if this is any useful information Smilie

The aim is to keep the files each in their folders, but just delete in B those which already exist in A

Code:
#!/bin/sh
vr=$(ls /path/to/FolderA)
for fl1 in ${vr};do
    echo "${fl1}"
done

vr2=$(ls /path/to/FolderB)
for fl2 in ${vr2};do
    echo "${fl2}"
done

Now make two arrays to save the result and compare those two arrays.
If there is any match then remove those files.

in ubuntu, you should be able to diff the folder directly.

Code:
diff /path/to/FolderA /path/to/FolderB
