Comparing 2 folders removing the files that are not there twice....

[thusgaard]

Hi

I have 2 folders containing files for a special timelapse video.
They have been shot with two cameras and named the same way.

All the pictures are amed like: 2013-01-11-07:58:17.jpg

My problem is that one folder has slightly more pictures than the other. (camera error)
So I want to compare folder 1 to folder 2, but only at file name level.
And remove the pictures that aren't represented in both folders (copying them to a new folder)

Can this be done and how?

the diff command should do it:

ls ./folder1 > file1
ls ./folder2 > file2
diff -s file1 file2

the diff command should do it:

ls ./folder1
ls ./folder2
diff -s file1 file2

Will that remove anything or just show the difference?

Dosn't this only work on one file. I have 2300+ files in both directories.

are these directories flat or have subdirs in them?

No subdirs, they are completely flat

ls ./folder1 > file1
ls ./folder2 > file2
diff -s file1 file2

Is there a way to

move the files in the diff list.
Say is I do like this:

diff -s file1 file2 > difffile

i am sure someone will come up with a more elegant code , but this is what I could get at the moment as fast as I could.

diff -qr ~/a ~/b | while read line ;
do  folder="$( echo $line | cut -d ":" -f 1| cut -d " " -f 3)"; 
file="$( echo $line | cut -d " " -f 4)"; 
path="$folder/$file"; 
cp $path ~/c ; 
done

copy and paste into the termianl one line at the time:

"~/a" and "~/b" are the folders to be compared
"~/c" ius the folder where you want to copy the file not in common


Note :
1-you have to change the path and the name of the folders based on your folders;
2- I used the copy command not the move "mv". Just to make sure you don't loose any data. Try it first then change "cp $path ~/c ; " with "mv $path ~/c ; " (or even better an IF condition that deletes the file only if the copy commands is succesfull)_
BE CAREFULL! "mv" COMMAND DOES NOT FORGIVE!!!

couldn't you just do something like

$ for file in dir2/*; do [ -f "dir1/${file##*/}" ] || cp "$file" newdir/; done

$ ls dir1
file1  file2  file3  file4  file5
$ ls dir2
file1  file2  file3  file4  file5  file6
$ 
$ for file in dir2/*; do [ -f "dir1/${file##*/}" ] || echo cp "$file" newdir/; done
cp dir2/file6 newdir/

file1  file2  file3  file4  file5  file6
$ 
$ for file in dir2/*; do [ -f "dir1/${file##*/}" ] || echo cp "$file" newdir/; done
cp dir2/file6 newdir/

I do not think the code copies the files present in dir1 AND not in dir2 . You copy only the files present in dir2 and AND in dir1.


can you posyt the content of new dir?

This worked for me:

$ cd folder1/
$ for file in `ls -1` ; do [ -f ../folder2/${file} ] || mv  $file /somefolder/ ; done

$ cd ../folder2/
$ for file in `ls -1` ; do [ -f ../folder1/${file} ] || mv  $file /somefolder/ ; done

Thanks for all your help.
