If we do a help we can see all the options it brings

Bash

rokitoh@red-orbita:~$ scp help

usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]

[-l limit] [-o ssh_option] [-P port] [-S program]

[[user@]host1:]file1 … [[user@]host2:]file2

Copy from local computer to remote computer.

Bash

rokitoh@red-orbita:~$ scp Archivo Usuario@Servidor:RUTA

Example:

Bash

rokitoh@red-orbita:~$ scp red-orbita.jpg rokitoh@red-orbita.es:/home/rokitoh/

rokitoh@red-orbita.es’s password:

red-orbita.jpg                                                              100% 268KB 267.6KB/s 00:0

In this example we have copied an image called “red-orbita.jpg” through a user “rokitoh” to remote host red-orbita.es, this file will be saved in the directory/home/rokitoh/we would make the connection

In the opposite case that we want to copy from the remote host to our local computer it would be like this:

Bash

rokitoh@red-orbita:~$ scp Usuario@Servidor:Ruta/Archivo Ruta_Local

Example:

Bash

rokitoh@red-orbita:~$ scp rokitoh@red-orbita.es:/home/rokitoh/red-orbita.jpg /tmp/

rokitoh@red-orbita.es’s password:

red-orbita.jpg                                               100% 268KB 267.6KB/s 00:00

We can copy entire folders using the -r argument

Bash

rokitoh@red-orbita:~$ scp -r Archivo Usuario@Servidor:RUTA

Example:

Bash

rokitoh@red-orbita:~$ scp -r Documentos/ rokitoh@red-orbita.es:/home/rokitoh

rokitoh@red-orbita.es’s password:

rokitoh@red-orbita:~$

As in previous cases we have copied the directory “Documents” in the folder /home/rokitoh from the server red-orbita.es.

To do this process in reverse, downloading from the server to our computer is totally the same process as before.

Bash

rokitoh@red-orbita:~$ scp Usuario@Servidor:Ruta/Archivo Ruta_Local

Example:

Bash

rokitoh@red-orbita:~$ scp -r rokitoh@red-orbita.es:/var/ww /home/rokitoh

rokitoh@red-orbita.es’s password:

rokitoh@red-orbita:~$

Can also be copied from 2 remote hosts

Syntax:

Bash

rokitoh@red-orbita:~$ scp Usuario@Servidor1:/home/rokitoh/Archivo Usuario@Servidor2:/Ruta

Example:

Bash

rokitoh@red-orbita:~$ scp rokitoh@192.168.1.104/home/rokitoh/red-orbita.jpg operador@192.168.1.109:/home/operador

In this last example a file would be copied from the server 192.168.1.104 with the user rokitoh al servidor 192.168.1.151 with the user operator.

Well, that's all for now, in the next few days I will publish a small SSH manual and I will explain how to make connections without authenticating.

Greetings, rokitoh!
