Transfers file or folder between a remote server (master node), compute node, and client machine can be easily possible with a scp command.
scp or secure copy allows secure transferring of files between between two remote hosts. It uses the same authentication and security as the Secure Shell (SSH) protocol from which it is based. A scp can transfers you both single or multiple files and folders simultaneously. It's simplicity, secure, and fast.
man scpHere is the normal syntax for single file transfer.
1. From a local machine to a remote machine,
scp file user@ip-address:/remote/directory/2. From a remote machine to a local machine,
scp user@ip-address:/remote/directory/file /local/directory/For sending multiple files, one can use regular expression "{" and "}" for grouping all files and send them all at the same time.
1. From a local machine to a remote machine,
scp file1 file2 file3 ... user@ip-address:/remote/directory/or
scp file.* user@ip-address:/remote/directory/or
scp file{1,2,3} user@ip-address:/remote/directory/2. From a remote machine to a local machine,
scp user@ip-address:/remote/directory/\{file1,file2,file3\} /local/directory/1. Specify port number of remote machine,
Syntax:
scp -P <port_number_of_remote> file1 file2 ... user@ip-address:/remote/directoryCaveat: For scp, you can specify port number using only "-P" (big P).
