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.
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 [email protected]
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 [email protected]:~/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 [email protected]:~/data/my-directory .
