I am trying to do something along the same lines as what is asked in this question: RSync: How do I synchronize in both directions?
However, what I can't figure out is whether or not I should add slashes to the end of the file path. Basically I'm trying to create an alias command that syncs the contents of two directories that go by the same name but are on two different servers. What I don't want is for one directory to be copied into the other (which I am aware is a possibility depending on how the slashes at the end are done).
What I have currently is:
alias syncDirectories1 = 'rsync -tvur name@host:/Users/me/directory/ /Users/me/directory/' alias syncDirectories2 = 'rsync -tvur /Users/me/directory/ name@host:/Users/me/directory/'
For what I am trying to accomplish, should there be slashes at the end of both file paths?
Thank you in advance for the help.
Rsync, or Remote Sync, is a free command-line tool that lets you transfer files and directories to local and remote destinations. Rsync is used for mirroring, performing backups, or migrating data to other servers.
Rsync (Remote Sync) is the most commonly used command for copying and synchronizing files and directories remotely as well as locally in Linux/Unix systems.
Usage. rsync works in one direction, so we need to run it twice to sync directories in both directions.
If you want to copy a file from one location to another within your system, you can do so by typing rsync followed by the source file name and the destination directory. Note: Instead of “/home/tin/file1. txt”, we can also type “file1” as we are currently working in the home directory.
It's described in the rsync(1)
manpage:
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/dest/foo
:rsync -av /src/foo /dest rsync -av /src/foo/ /dest/foo
As to the destination, I don't think it has any major consequences. There is a difference if the source is a file and destination doesn't exist — this will make a copy of SRC
called DEST
:
rsync SRC DEST
, whereas, this will create directory DEST
and copy the SRC
file into it:
rsync SRC DEST/
I tested it with rsync 3.1.3 on Arch Linux, the results are below:
1. rsync -avPzu test login@remote:/home/login/test "test" directory is copied inside of existing "test" on remote (structure is then test/test/...) 2. rsync -avPzu test login@remote:/home/login/test/ same as above 3. rsync -avPzu test/ login@remote:/home/login/test content of "test" directory is synchronized with the remote "test" directory 4. rsync -avPzu test/ login@remote:/home/login/test/ same as above 5. rsync -avPzu test login@remote:/home/login/ same as above 6. rsync -avPzu test login@remote:/home/login same as above
The methods 3-6 are the correct ones in this case, contrary to the accepted answer.
