Hello everyone.
I have a "/source-folder/" which contains very large tree of folders and
files.
I've manually copied a set of folders and files from it to a
"/destination-folder-one/" and
copied another set of folders and files to a "/destination-folder-two/".
Now, is there an effective way to compare combined contents of two
folders "/destination-folder-one/" and
"/destination-folder-two/" against a "/source-folder/" to show if there
is anything that was left out?
For now I've tried "diff" and "rsync" to accomplish this.
But diff apparently can't compare combined contents of two folders with
another folder.
$ diff -r /destination-folder-one/ /destination-folder-two/
/source-folder/
diff: extra operand '/source-folder/'
diff: Try 'diff --help' for more information.
And rsync scans folders and files that are already exist inside both
destination folders and "/source-folder/" and outputs nothing.
$ rsync -r --size-only --dry-run /destination-folder-one/
/destination-folder-two/ /source-folder/
$
I could go on a wild chase to "ls" contents of both destination folders,
concatenate the results, sort them somehow,
do the same to a source folder and compare the resulting list files.
Also create test cases to check if results are reliable.
But before I do that, is there a better way to accomplish the task?
Maybe some parameter for diff or rsync that I missed or another utility?

With kindest regards, Alexander.
