Linux administrators should be familiar with the command-line environment. Since GUI (Graphical User Interface) mode in Linux servers is not commonly installed.

SSH may be the most popular protocol to enable Linux administrators to manage the servers securely from a remote location. Built into the SSH command is the SCP command, which is used to copy file(s) between servers securely.

Basic Syntax of SCP Command

The below command will read as copy “source_file_name” into “destination_folder” at “destination_host” using the “username” account.

<code>scp source_file_name username@destination_host:destination_folder</code>

There are many parameters in the SCP command that you can use. Here are the parameters that may be used on a daily basis.

Table of Contents

The basic SCP command without parameters will copy the files in the background. Users will see nothing unless the process is done or some error appears.

You can use the “-v” parameter to print debug information onto the screen. It can help you debug connection, authentication, and configuration problems.

Copy File From Local Host to Remote Server

The following command copies a file “scp-cheatsheet.pdf” from a local to a remote Linux system under /home/tecmint directory.

<code>$ scp -v scp-cheatsheet.pdf [email?protected]:/home/tecmint/.</code>

Sample Output:
