Is there a way to retrieve a secure copy in UNIX?

Why would I need to do this? Because I can login to a remote machine from my local machine, but not the other way around. So I need to retrieve a secure copy instead of just using scp to send a file from my remote machine to my local machine.

    What's the difference between "retrieve a secure copy" and "use scp to send a file from remote to local"? Why is the latter not sufficient? – glenn jackman Jul 21 '14 at 13:15

scp can be used both to copy to a remote machine, and from one:

I assume you are used to using:

scp localfile USER@REMOTE:remotefile

But you can also use it to do:

scp USER@REMOTE:remotefile localfile

  • Worked!! Is there a way to get this to append to that local file, however? – MrPickles Jul 21 '14 at 13:27
  • To my knowledge, not without going via a temporary file – Andrew Stubbs Jul 21 '14 at 13:29

To append a remote file to a local one, improving Andrewe Stubbs answer copy to local stdout and append that:

 scp USER@REMOTE:remotefile /dev/stdout >> localeppendedfile

or simply (assuming a Posix remote machine)

 ssh USER@REMOTE /bin/cat removefile >> localeppendedfile
