Just to clarify, you can avoid specifying both username and host in origin and destination, and the scp command will work just like the cp command, copying a local file to a local destination. And in the same way as with origin, if the host is not specified, the files will be copied locally. Same as above if the user is not specified but a hostname is given it will defaults to the current username and will try to log in the remote server using that user. The destination, where you specify the path where the files are going to be copied, once again, it can contain or not the information about the remote host and/or user in that host. If the host is not specified, it will look for the file locally using any given path. If the user is not specified it will defaults to the current user in the machine where you are typing the command. The origin, where you specify the file or files to be copied, it can contain or not the information about a remote host, and it can also contain the information about the user owning the file or files in that remote host. Is the command itself and tells the operating system to copy one or more files over a secure shell connection, better known as ssh connection. We are going to explain the basic part of it: scp. the complete syntax and every option of scp command is out of the scopy of this page, you can always enter a the command prompt man scp We will learn in this tutorial about the basic use of the command, and some useful examples and scenarios where you can use it. You can use scp on Linux, Mac and Windows (using WinSCP). In the last case the traffic goes directly from one server to the other without passing through your system, that is a good thing if you have a slow Internet connection Securely copy files from one remote computer to another remote computer.Securely copy files from your computer to remote compueters.Securely copy files from remote computers to your computer.You can use scp command in these scenarios: Scp uses by default the port 22, and connect via an encrypted connection or secure shell connection. That connection will be securely encrypted, it is a very secure way to copy files between computers. The second does what an Option-drag does, or what happens when you drag a file to a different disk or volume.Scp stands for secure cp (copy), which means you can copy files across ssh connection. The first does the same as dragging a file to a new location on the same hard disk. There are two commands for moving and copying: mv and cp. The same is the case from the command line. (You may know that you can copy a file in the Finder, even on the same hard disk, by holding down the Option key when you drag it.) However, if you drag a file from your Desktop to an external hard disk, you’ll see that the file remains in its original location this file has been copied. The file is no longer on the Desktop, and is found only in the Documents folder. If you’re in the Finder, and you drag a file from, say, your Desktop to your Documents folder, or any other folder on the same disk or volume, you move the file. The difference between copying and moving files If you’ve lost access to the Finder because your Mac is on the blink, you might be able to use the command line to troubleshoot the problem.You can copy or move multiple files using wildcards.These files, which can contain settings for certain apps or parts of the Mac, contain a dot (.) before their names, and the Finder doesn’t show them. You can copy or move files that are hidden in the Finder.You can copy or move files from one location to another without opening windows in the Finder.
