            Bug ID: 11253
           Summary: --exclude=dir doesn't work with --files-from          
Product: rsync
           Version: 3.1.1
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core

Reproducer/test case

If I just pass --exclude=file or --exclude=dir to rsync, the file or dir is
excluded correctly.

However, if you pass a list of files in --files-from= that includes the file I
want to exclude, then only --exclude=file works as before; --exclude=dir
doesn't seem to do anything at all.

As a workaround, I've found that --exclude=dir/** will actually exclude dir,
as
I originally wanted.

This behaviour is counter-intuitive to me; at the very least, I'd expect
--exclude=dir to work the same as --exclude=file.

I've checked that the behaviour is present in latest git master. I've
also
included a simple reproducer script (uncomment 1 of the 4 rsync commands and
run it to see the result of the transfer).

--- Comment #1 from Wayne Davison <wayned at samba.org> ---
Excludes don't affect args, just items that are found in recursion. A
files-from list is the same as specifying all the names as args on the
command-line, and thus are not affected.  Specifying an exclude of just the dir
name matches only that dir itself, so when recursing inside the dir, that rule
won't match anything.  If you don't want a particular arg to be
included, you
can filter it out of the files-from file.  Your exclude of dir/** (or dir/***)
is also a good solve, as it tells rsync to affect the contents of a particular
path.

One filter solution:

egrep -v '/dir(/|$)' files_from | rsync -aiv --files-from=- / /to/
