rsync - including only certain extensions

[chantron]

Hey!

I run some backup scripts using rsync and in order to cut down on the filesize, I only want to backup the files with certain extensions (ie .bmp/.jpg/.css etc...).

My question is that if I use --include *.bmp will I have to use --exclude *.* (or something) too? After reading the man pages I'm just a little confused!

Does anyone know of a way to get this done?

Thanks a lot

For local copying, it doesn't matter. For remote copying you can tell rsync to use SSH with the -e flag, like this:

rsync -e /bin/ssh

To answer the original question, you can do something like this:

rsync -av  --include="*yes" --exclude="*" -n 1/ 2/

In my example, the directory 1 has files named a.yes, a.no, b.yes, b.no, etc. When the above command is run, only the *yes files get copied. Take note: rsync cares what comes first. If you put the exclude first, nothing gets copied.
