To securely copy files across a network computer in Linux or UNIX, you can use the scp command.
The scp command is a secure version of the cp command that is used to copy files between computers over a network. It uses the SSH (Secure Shell) protocol to securely transfer the files.
To use the scp command, you will need to specify the source file and the destination file. The source file is the file that you want to copy, and the destination file is the location where you want to copy the file.
To copy a file from your local computer to a remote computer, you can use the following scp command:
$ scp source_file username@remote_host:destination_file
This will copy the source_file from your local computer to the destination_file on the remote computer. The username is the user account on the remote computer, and the remote_host is the hostname or IP address of the remote computer.
To copy a file from a remote computer to your local computer, you can use the following scp command:
$ scp username@remote_host:source_file destination_file
This will copy the source_file from the remote computer to the destination_file on your local computer.
You can also use the scp command to copy multiple files at once. To copy multiple files, you can specify the source files and the destination directory. For example, to copy multiple files from your local computer to a remote computer, you can use the following scp command:
$ scp file1 file2 file3 username@remote_host:destination_directory
This will copy the file1, file2, and file3 files from your local computer to the destination_directory on the remote computer.
Note that you will need to have an SSH client and server installed on the local and remote computers to use the scp command. You can use the ssh command to connect to the remote computer and transfer files using scp.
