Background

We can transfer files to the OSG Connect login host using the Unix scp command. Note scp is a counterpart to the secure shell command,ssh, that allows for secure, encrypted file transfers between systems using your ssh credentials.

Steps

To transfer a file using scp, you'll need to run scp with the source and destination. Files on remote systems are indicated using user@machine:/path/to/file.

First, log in using your OSG Connect user id (username): 

$ ssh username@login.osgconnect.net

Once logged in, change to the data directory, a link from your home area:

$ cd ~/data

This directory is area on the Stash data server that you can use to store files and directories. It functions just like any other UNIX directory although it has additional functions that we'll go over shortly. 

Let's create a file:

$ echo "Hello world" > my_hello_world

Now copy the file just created from Stash to our local system (Desktop or laptop):

$ scp username@login.osgconnect.net:~/data/my_hello_world .

As you can see, scp uses similar syntax to the cp command. To copy directories using scp, you'll just pass the (recursive) -r option to it. 

For example:

$ scp -r username@login.osgconnect.net:~/data/my-directory .
