通过R中的SCP发送文件

Question

I would like to copy a file from my computer to a remote server via SCP using R .

I have found 2 functions that appear to satisfy this partially.

1. Using ssh.utils

ssh.utils::cp.remote(path.src="~/myfile.txt",
                     remote.dest="username@remote",
                     remote.src="", path.dest="~/temp", verbose=TRUE)

I've noticed that with this method, if I need to enter a password (when remote doesn't have my public key), the function produces an error.

2. Using RCurl :

RCurl appears to have more robust functionality in the scp() function, but, from what I can tell, it is only for copying a file from a remote to my local machine. I would like to do the opposite.

Is there another way to use these functions or is there another function that would be able to copy a file from my local machine to a remote machine via SCP?

Answer 1

One approach to address the need to enter a password interactively is to use sshpass (see https://stackoverflow.com/a/13955428/6455166 ) in a call to system , eg

system('sshpass -p "password" scp ~/myfile.txt username@remote.com:/some/remote/path')

See the linked answer above for more details, including options to avoid embedding the password in the command.
