I'm familiar with rsync, but having trouble with one issue..

I want to be able to sync files from multiple directories to one directory. If I remove a directory from the source list, then I want that directory and all of its files to be removed from the destination.

Here's a quick sample:

mkdir dir1

touch dir1/file1

mkdir dir2

touch dir2/file2

mkdir dir3

rsync -a dir1 dir2 dir3

dir3 now contains "dir1/file1" and "dir2/file2".

If I rsync again, and remove dir2 from the list:

rsync -a dir1 dir3

Then I would like dir2/file2 and dir2 to be removed from the destination.

The --delete option to rsync only handles deletes between dir1 and dir3/dir1, so dir2 remains (even if using --delete).

I've looked through the various option in the man page for rsync, and I don't see any option that tells rsync to "combine" all the sources and consider them as "one" tree so that "--delete" would do what I want it to do. However, I'm pretty confident I'm not the first person to want to do something like this.

Ideas?

  I think it's not possible using the syntax that you want. I think you nail it with your last paragraph. rsync doesn't "know" about dir2, so it won't delete it.

The --delete flag obviously doesn't work if you sync multiple source directories to one destination directory. Instead of syncing dir1 and dir2 to dir3 you could sync the content of parent dir of dir1 and dir2.

Example (using rsync flag -i to see the changes):

$ mkdir -p dir12/dir1 dir12/dir2 dir3

$ touch dir12/dir1/file1 dir12/dir2/file2

$ rsync -ai dir12/ dir3

cd+++++++++ dir1/

>f+++++++++ dir1/file1

cd+++++++++ dir2/

>f+++++++++ dir2/file2

# BEFORE: dir1 and dir2 were synced to dir3

$ rm -rf dir12/dir2

$ rsync -ai --delete dir12/ dir3

*deleting   dir2/file2

*deleting   dir2/

.d..t...... ./

# AFTER: dir3/dir2 is gone

If you don't have a common parent directory, then dir12/dir2 could be a symlink pointing to the real directory. With option -L (--copy-links) in the first rsync call you would get the same directory structure in dir3 with dir2 as directory (instead of a symlink). And after deleting symlink dir12/dir2 and syncing again with --delete the directory dir3/dir2 would be gone like in the example.

The --delete flag obviously doesn't work if you sync multiple source directories to one destination directory. Instead of syncing dir1 and dir2 to dir3 you could sync the content of parent dir of dir1 and dir2.

Example (using rsync flag -i to see the changes):

$ mkdir -p dir12/dir1 dir12/dir2 dir3

$ touch dir12/dir1/file1 dir12/dir2/file2

$ rsync -ai dir12/ dir3

cd+++++++++ dir1/

>f+++++++++ dir1/file1

cd+++++++++ dir2/

>f+++++++++ dir2/file2

# BEFORE: dir1 and dir2 were synced to dir3

$ rm -rf dir12/dir2

$ rsync -ai --delete dir12/ dir3

*deleting   dir2/file2

*deleting   dir2/

.d..t...... ./

# AFTER: dir3/dir2 is gone

If you don't have a common parent directory, then dir12/dir2 could be a symlink pointing to the real directory. With option -L (--copy-links) in the first rsync call you would get the same directory structure in dir3 with dir2 as directory (instead of a symlink). And after deleting symlink dir12/dir2 and syncing again with --delete the directory dir3/dir2 would be gone like in the example.
