I am attempting to copy only certain files down a directory tree. I
know which files I want. I could generate a file of just those with
'find'. But having read the docs I have been trying to use the
--include and --exclude patterns to have rsync pick the right files
itself. But I can't figure it out. I am suspecting that I can't do
what I want to do.
Source example, this is what I have, foos and bars are files:
dir1/a1/foo
dir1/a2/foo
dir1/a3/bar
dir1/bar
dir2/a1/foo
dir2/a2/foo
dir2/a3/bar
dir2/bar
Destination example, this is what I want, just the foos:
dir1/a1/foo
dir2/a1/foo
Here is how I am trying to do it.
rsync -a --include '**/a1/foo' --exclude "*" . example.com:/tmp/
But that does not match any files. "0 files to consider" is the
result. The man page has an example with --include "*/".
rsync -a --include '*/' --include '**/a1/foo' --exclude "*" . example.com:/tmp/
That does too much and creates all of the directories even if there is
no file "foo" in the directory. That is, in my example above all of
the */a2 directories are also copied.
Can anyone think of a way to do this?
The actual source directories are relatively large with 20k total
files or so in a deep hiearchy tree. So expanding them on the command
line is not good since it will frequently exceed ARG_MAX.
Conceptually something like the following would work if the directory
was not too big and I could also line up the destination to match the
source.
rsync -a $(find . -name foo -print) example.com:/tmp/ # bad example
for file in $(find . -name foo -print); do # another bad example
dirname=$(dirname $file)
rsync -a $file example.com:$dirname/ # 20k times seconds per ssh...
done
That is just very, very slow. I can almost use fsh but just the same
it would be much cleaner to do this entirely within rsync.
Thanks
Bob
