How to download a file from server using SSH? [closed]

In your terminal, type:

scp your_username@remotehost.edu:foobar.txt /local/dir

replacing the username, host, remote filename, and local directory as appropriate.

If you want to access EC2 (or other service that requires authenticating with a private key), use the -i option:

scp -i key_file.pem your_username@remotehost.edu:/remote/dir/foobar.txt /local/dir

From: http://www.hypexr.org/linux_scp_help.php

You can do this with the scp command. scp uses the SSH protocol to copy files across system by extending the syntax of cp.

Copy something from another system to this system:

scp username@hostname:/path/to/remote/file /path/to/local/file

Copy something from this system to some other system:

scp /path/to/local/file username@hostname:/path/to/remote/file          

Copy something from some system to some other system:

scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file   

scp is certainly the way to go, but for completeness you can also do:

$ ssh host 'cat /path/on/remote' > /path/on/local

or

$ cat /path/on/local | ssh host 'cat > /path/on/remote'

Note, this is UUOC, but < /path/on/local ssh host 'cat > /path' could cause unnecessary confusion.

And to proxy between two hosts:

$ ssh host1 'cat /path/on/host1' | ssh host2 'cat > /path/on/host2'
