Rsync ignores dry-run

rsync

I have just run the following command in a bash script

rsync -av -update  --dry-run --delete $EX "$FROM" "$TO"

the sync ran, --dry-run was ignored (luckily that was ok this time).

Does any one see any reason why --dry-run would be ignored here?

That's because the correct option is --update, not -update. Your command should be:

rsync -av --update --dry-run ...

When rsync does the dry-running, the last line of default rsync stat output will show the string (DRY RUN) e.g.:

total size is 0  speedup is 0.00 (DRY RUN)

Full output:

% rsync -av --update --dry-run foobar out/
sending incremental file list
foobar

sent 62 bytes  received 19 bytes  162.00 bytes/sec
total size is 0  speedup is 0.00 (DRY RUN)

How rsync –compare-dest works

I had the same trouble, you have to do:

rsync -avh --dry-run                                          \
      --compare-dest=/run/media/user/centos6/updates/x86_64/  \
      /home/REPOS/6/updates/x86_64/Packages                   \
      /path/to/updates

Note --compare-dest is the parent of Packages and do not put / at the end of source folder!

Does rsync delete files on the destination that were deleted from the sending side

Only if you… select one of the delete options. See man rsync for more information, but here is an excerpt:

--delete                delete extraneous files from dest dirs
--delete-before         receiver deletes before xfer, not during
--delete-during         receiver deletes during the transfer
--delete-delay          find deletions during, delete after
--delete-after          receiver deletes after transfer, not during
--delete-excluded       also delete excluded files from dest dirs

There is more detailed information for these options further down the man page.
