SCP (SSH)
Secure copy, or SCP, is just that -- a means of securely copying files. Unlike the regular cp command, this command allows you to transfer files between two computers using the SSH protocol to provide both authentication and encryption.
Working on a model of SOURCE and DESTINATION, SCP allows you to:
Provided that we know usernames and passwords for a user on your current system and a user on the remote system. For example, let's copy an example file from our machine to a remote machine, which I have neatly laid out in the table below:
With this information, let's craft our scp command (remembering that the format of SCP is just SOURCE and DESTINATION)
scp important.txt [email protected]:/home/ubuntu/transferred.txt
And now let's reverse this and layout the syntax for using scp to copy a file from a remote computer that we're not logged into
The command will now look like the following: scp [email protected]:/home/ubuntu/documents.txt notes.txt
