These options can be used to specify the target system, the file or directory to be transferred, the user to log in as, and the authentication method. The SCP command has several options that can be used to control the command’s behavior. If you try and use the SCP command and receive an error such as bash: scp: command not found, then you need to install SCP on either your local or remote server.įedora or Red Hat Enterprise Linux and clones (CentOS): yum -y install openssh-clientsĭebian or Ubuntu: apt-get install openssh-client SCP Command Options The SCP command comes pre-installed on Mac and dedicated Linux servers, so no additional installation is typically required. The SCP command also supports various options that can be used to customize the transfer. The destination can be either a local directory or a remote directory. The source can be either a local file or a directory. To use SCP, you must have both the source and destination computers on the same network. This means that the data is safe from interception while in transit and only the user with the correct key can access the data. It uses public-key cryptography to encrypt the data and authenticate the user. The SCP command works by establishing an SSH connection between two computers and then copying files from one computer to the other. However, when copying multiple files, you must specify the file name as the source path. The portion is optional and is used to specify the username for authentication when connecting to the remote host. You can use the SCP command to securely copy multiple files from a source host to a destination host.įor instance, the basic syntax for this command is: scp source_file source_file is the file you want to transfer, and the destination_file is the location to which you want the file to be copied. The SCP command supports various options that you can use to customize how the file is copied.

It is typically used to copy files from a local computer to a remote server or from remote servers to a local computer. SCP (Secure Copy) is a command-line utility that uses SSH to securely transfer files between computers, allowing for secure authentication, encryption, and data integrity. SCP stands for Secure Copy Protocol and is a way to transfer files from one computer to another securely. See Also: Meet ServerMania: Transform Your Server Hosting Experience What is an SCP Command? This article will provide practical examples of how to use this command. I'd go with the subprocess module if using version 2.4+.The SCP command can be used to transfer files between servers securely. If opting for the system-call path, Python offers an array of options such as os.system or the commands/subprocess modules. I gave Conch the once-over some time ago but it didn't appeal to me. I've used Paramiko with an eye towards replacing system calls but found myself drawn back to the wrapped commands due to their ease of use and immediate familiarity. NOTE: its hard to beat rsync if you plan on transferring files via SSH, especially if the alternative is plain old scp. It probably goes without saying that SSH keys are almost always a better idea than passwords for this sort of stuff. You will need to setup SSH keys to enable password-less logins if you are wrapping system commands like "ssh", "scp" or "rsync." You can embed a password in a script using Paramiko or some other library, but you might find the lack of documentation frustrating, especially if you are not familiar with the basics of the SSH connection (eg - key exchanges, agents, etc). use a Python library that provides SSH capabilities (eg - Paramiko or Twisted Conch)Įach approach has its own quirks.There are a couple of different ways to approach the problem:
