https://bugzilla.samba.org/show_bug.cgi?id=13587

            Bug ID: 13587
           Summary: Add a --dry-run way to show destination for each item
           Product: rsync
           Version: 3.1.2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
          Assignee: wayned at samba.org
          Reporter: jidanni at jidanni.org
        QA Contact: rsync-qa at samba.org

User very much wants to know where the files _will go_ before daring to try an
actual run.

He tries even
rsync -vv --dry-run --itemize-changes -avz x.y.z:dir1/dir2/backup/ backup/

but still there is no way to make it say
File x.y.z:dir1/dir2/backup/F1 will be copied to backup/F1
File x.y.z:dir1/dir2/backup/F2 will be copied to backup/F2

What about that:

  with this hierarchy:

    find dir1 dir3
    dir1
    dir1/dir2
    dir1/dir2/backup
    dir1/dir2/backup/subdir
    dir1/dir2/backup/subdir/F3
    dir1/dir2/backup/F2
    dir1/dir2/backup/F1
    dir3
    dir3/backup
    dir3/backup/F4

  one may say, for two source directories:

    rsync --dry-run --out-format='%i %f -> %n%L' -a dir1/dir2/backup/
dir3/backup/ backup/
    cd+++++++++ dir1/dir2/backup/. -> ./
    >f+++++++++ dir1/dir2/backup/F1 -> F1
    >f+++++++++ dir1/dir2/backup/F2 -> F2
    >f+++++++++ dir3/backup/F4 -> F4
    cd+++++++++ dir1/dir2/backup/subdir -> subdir/
    >f+++++++++ dir1/dir2/backup/subdir/F3 -> subdir/F3

Ref: man rsyncd.conf: log format

 %i an itemized list of what is being updated
 %f the filename (long form on sender; no trailing "/")
 %n the filename (short form; trailing "/" on dir)

--- Comment #1 from Dan Jacobson <jidanni at jidanni.org> ---
Thank you for https://lists.samba.org/archive/rsync/2018-August/031701.html

I was hoping for something simple like
$ cp -v m n
'm' -> 'n'

i.e., like a theoretical cp --dry-run -v
with no need for complicated %'s.
