I need to synchronize the content of folders. Lets say I have 2 folders : - /home/hans/folder1 - /home/hans/folder2 Everytime I change something in folder1 like remove a file, create a file etc, folder2 will automatically be synchronized at once. how do i do that? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello Hans, It depends on what you really want to achieve by "synchronize". 1. If you just want to make an 'impression' that anything happens in folder1 will be 'synchronized' instantly to folder2, then you can mount --bind folder1 to folder2: mount --bind /home/hans/folder1 /home/hans/folder2 2. But if you want to provide a backup function too, so that if anything happens in folder1, there is a backup available in folder2, you can use rsync: rsync -a /home/hans/folder1 /home/hans/folder2 And put that command in crontab for to be running say.. 3 minutes.

I wonder if there would be an easy way using 'famd' instead. - -- Cheers, Carlos E.

It is running on suse systems by default. Not on my OpenSUSE 10.2

I'd never heard of it before. I checked and found you man page. But no output from the command: ps -e | grep fam John O'Gorman

File Access Monitoring Daemon? IIRC it's been discussed on the list a few times. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Gee thanks, Carlos. Further investigation into this has added yet another "gotta work on this" mini-project to my list! Looks cool and a simple folder synchronizer should be reasonably easy to do. -- Jonathan Arnold (mailto:jdarnold@buddydog.org) Daemon Dancing in the Dark, an Open OS weblog: http://freebsd.amazingdev.com/blog/ UNIX is user-friendly.

I'd be interested in knowing the result ;-) Kind of a cute daemon "a la cron" would be nice. You know, define a file with lines like: d|f path_to_dir_or_file_to_watch program_or_script_to_execute O:-) - -- Cheers, Carlos E.

You could create a link from one folder to the other. That way, you have one folder appearing as two. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It comes with the distro. But it is not automatic, AFAIK. - -- Cheers, Carlos E. R.
