Secure shell, remotely login on a machine running the sshd daemon. Once you are logged in you have a secure shell and are able to execute various commands on that computer such as copy files, reboot the computer, just like it was your own GNU/Linux PC.
scp machineToBeCopiedFrom machineToBeCopiedTo
Where either machine can be a local directory (on the current filesystem /) or a remote machine. Remote machines are usually machinesFullName:/directory (if you omit the directory part it will just assume the home directory of the username you are logging in with).
The example below copies all files from the current directory (not including any directories), the command will login to “new” using the username of the person currently logged in on the local computer, the files will be copied to the root directory of the remote computer called “new” (which is probably on the LAN):
scp * new:/
You could also copy files from another computer to another computer. Let's say you are on a computer called “p100”. And you want to copy files (and directories) from “hp166” (in the /tmp directory and anything below that) to “new” and put the files in new's temporary directory. You could do:
scp -r hp166:/tmp new:/tmp
scp -r root@hp166:/tmp anon@new:/tmp
scp remoteMachine:/mystuff/* .
Remote Machines: Please note that when working with a remote machine you need to have a : (colon) after the machine name even if you want the files in their home directory. Otherwise the command will fail.
The command usage is very similar to ftp (the command-line tool), sftp (once running) uses commands such as help (for help), put (send files to the server), get (download files from the server) and various others, refer to the manual page and internal documentation for further details.
