I have two remote Debian servers, A and B. How can I copy a directory of files at `~/Documents/training_results` existing on server A to the path `~/training_results` on server B? I have SSH access on my local laptop to each of the servers, but neither of the servers have SSH access to the other.<|im_end|>

To copy files from one computer to another using SSH, you can use the SCP (Secure Copy Paste) program. SCP comes default in OpenSSH on many distributions. Use the following command.

```
$ scp -r <user>@<server_a ip>:~/Documents/training_results <user>@<server_b ip>:~/training_results
```

Now I will explain what this command does. 

The ```-r``` option is to copy directory(s) recursively. 
Then you enter the User you want and the IP address for server A, then a colon. The directory we will copy is ```training_results``` from the ```Documents``` folder at the user ```home``` directory. 
Next, you enter the User you want and the IP address for server B, and then we do the same thing and enter the path where we will be pasting the file(s)/directory(s). 

I hope this helps!<|im_end|>

Thank you. Can you explain in more detail with better organization?<|im_end|>

Here's a more detailed explanation with better organization:

To copy a directory from one Debian server to another, you can use SCP (Secure Copy), which is a program in OpenSSH. Here's the basic command structure:
scp -r <user>@<source_server_ip>:<source_directory> <user>@<destination_server_ip>:<destination_directory>

Now, let's apply this structure to your specific use case:

scp -r <user>@<server_a_ip>:~/Documents/training_results <user>@<server_b_ip>:~/training_results

Explanation:

-r: The -r option is used to copy directories recursively, meaning it will copy all the files and subdirectories in the source directory.
<user>: Replace this with the username you use to SSH into each server.
<server_a_ip>: Replace this with the IP address of server A.
~/Documents/training_results: This is the source directory on server A that you want to copy. It's located at ~/Documents/training_results (the user's home directory on server A).
<server_b_ip>: Replace this with the IP address of server B.
~/training_results: This is the destination directory on server B where you want to copy the files. It's located at ~/training_results (the user's home directory on server B).
That's it! Run this command on your local laptop and it will copy the directory from server A to server B over SSH.<|im_end|>

Does this only work in Unix and Unix based systems? if so what can I do in other systems such as windows or OSX? another question is will ffiles be overwritten?<|im_end|>

The scp command is available on Unix-based systems such as Linux and macOS, but it is not natively available on Windows.

To copy files between servers on a Windows system, you have several options:

    Use a third-party tool such as WinSCP, which provides a graphical user interface for securely copying files between servers using the SCP (Secure Copy) protocol.

    Use the sftp (Secure File Transfer Protocol) command in combination with a Unix-like environment such as the Windows Subsystem for Linux (WSL) or a third-party tool such as Cygwin or Git Bash. The sftp command is similar to the scp command and allows you to securely copy files between remote servers.

Regarding your second question, by default, the scp command will overwrite any existing files with the same name in the destination directory. If you want to preserve the existing files, you can add the -n option to the scp command, which will prevent it from overwriting existing files:

ruby

scp -n -r userA@serverA:~/Documents/training_results userB@serverB:~/training_results

In conclusion, while the scp command is primarily available on Unix-based systems, there are alternative solutions available for Windows systems. Additionally, the scp command will overwrite existing files with the same name in the destination directory, but this can be prevented by using the -n option.<|im_end|>
