Re: [LUAU] rsync question
Nice, thanks Vince...the man pages are more than a little confusing on this
topic but logically the -delete option should mean that the default is no
delete. I should have just done a test case (like you did) so thanks for
the sledge hammer over the head.

Re: [LUAU] rsync question
The files are only removed when —delete is passed. Let’s verify:
foo$ mkdir src dst
foo$ touch src/{1,2,3,4,5}
foo$ rsync -av src/ dst/
building file list ... done
./

foo$ rsync -av src/ dst/
building file list ... done
./
sent 101 bytes received 26 bytes 254.00 bytes/sec

foo$ ls -1 src

Re: [LUAU] rsync question
I thought so too, but all the docs I've been finding seems to indicate that it deleteswhich doesn't work for me.

Re: [LUAU] rsync question
isn't the default behavior to keep files on the target? i think you have to use the --delete option to force delete from the target. So I'm trying to find if rsync has an option to NOT delete remote files if they're no longer on the local machine. The issue is that I can't afford to lose any data off my sensors. I've got the remote server mounted in fstab so that it looks like two local directories. I want to make sure everything in the local directory is copied and synced (updated) to the remote. But if someone deletes a file on the local machine but the file exists on the remote side, I don't want that remote file deleted. I've been searching like crazy, but rsync always seems to want to delete the remote file. Should I consider something other than rsync? /brian chee ___ LUAU@lists.freesoftwarehawaii.org mailing list http://lists.freesoftwarehawaii.org/listinfo.cgi/luau-freesoftwarehawaii.org
