Here is a cheatsheet for SCP (Secure Copy) - a program for transferring files over SSH.
Copy the file "foobar.txt" from a remote host to the local host
scp your_username@remotehost:foobar.txt /some/local/directory
Copy the file "foobar.txt" from the local host to a remote host
scp foobar.txt your_username@remotehost:/some/remote/directory
Recursively copy entire directories
scp -r user@your.server.example.com:/path/to/foo /home/user/Desktop/
Copy the directory "foo" from the local host to a remote host's directory "bar"
scp -r foo your_username@remotehost:/some/remote/directory/bar
Copy the file "foobar.txt" from remote host "rh1" to remote host "rh2"
scp your_username@rh1:/some/remote/directory/foobar.txt your_username@rh2:/some/remote/directory/
Copying the files "foo.txt" and "bar.txt" from the local host to your home directory on the remote host
scp foo.txt bar.txt your_username@remotehost:~
Copy the file "foobar.txt" from the local host to a remote host using port 2264
scp -P 2264 foobar.txt your_username@remotehost:/some/remote/directory
Copy multiple files from the remote host to your current directory on the local host
scp username@remotehost:/some/remote/directory/\{a,b,c\} .
scp username@remotehost:~/\{foo.txt,bar.txt\} .
To copy all from Local Location to Remote Location (Upload)
scp -r /path/from/local username@hostname:/path/to/remote
Copy all from Remote Location to Local Location (Download)
