I tried to use the --filter option in rs ... / 2010-01-06

I tried to use the --filter option in rsync but I was a bit baffled by the syntax and the manpage is nice but I couldn't understand. I wanted certain directories completely, other directories default excluded and certain files in one directory but not all. After some trail and error and talking to the teddybear:

rsync -rvv --progress /home/koos/rsyncsource/ /home/koos/rsyncdest --filter='merge /home/koos/rsyncfilter'

And in the filter file name things to include and exclude:

+ /wel/
- /niet/
+ /random/file
- /random/*

And the result is what I want:

$ ~/bin/testrsync 
building file list ... 
[sender] showing directory wel because of pattern /wel/
[sender] hiding directory niet because of pattern /niet/
[sender] hiding file random/niet because of pattern /random/*
[sender] showing file random/file because of pattern /random/file
7 files to consider

Now to do this on a filesystem with 151000 files.
