I usually read the man page before using a command.
So, when I use
rsync, I use the
-av options which is akin to
EDIT (after your comment):
The exact same happened to me, maaaany moons ago, I read the USAGE section and sure enough, it is written there (AFTER THE VERY FIRST EXAMPLE):
Note that the expansion of wildcards on the commandline (*.c) into a list of files is handled by the shell.... I also noticed that
-r does not preserve dates and
-v is also handy, I thought
-av would be perfect.
From the man page:
You use rsync in the same way you use rcp. You must specify a source and a destination, one of which may be remote.
Perhaps the best way to explain the syntax is with some examples:
rsync -t *.c foo:src/
This would transfer all files matching the pattern *.c from the current directory to the directory src on the machine foo. If any of the files already exist on the remote system then the rsync remote-update protocol is used to update the file by sending
only the differences in the data. Note that the expansion of wildcards on the commandline (*.c) into a list of files is handled by the shell before it runs rsync and not by rsync itself (exactly the same as all other posix-style programs).
rsync -avz foo:src/bar /data/tmp
This would recursively transfer all files from the directory src/bar on the machine foo into the /data/tmp/bar directory on the local machine. The files are transferred in "archive" mode, which ensures that symbolic links, devices, attributes, permissions,
ownerships, etc. are preserved in the transfer. Additionally, compression will be used to reduce the size of data portions of the transfer.
rsync -avz foo:src/bar/ /data/tmp
A trailing slash on the source changes this behavior to avoid creating an additional directory level at the destination. You can think of a trailing / on a source as meaning "copy the contents of this directory" as opposed to "copy the directory by name",
but in both cases the attributes of the containing directory are transferred to the containing directory on the destination. In other words, each of the following commands copies the files in the same way, including their setting of the attributes of
rsync -av /src/foo /dest
rsync -av /src/foo/ /dest/foo
Note also that host and module references don’t require a trailing slash to copy the contents of the default directory. For example, both of these copy the remote directory’s contents into "/dest":
rsync -av host: /dest
rsync -av host::module /dest
You can also use rsync in local-only mode, where both the source and destination don’t have a ’:’ in the name. In this case it behaves like an improved copy command.
Finally, you can list all the (listable) modules available from a particular rsync daemon by leaving off the module name:
