The copy_cluster_copy.sh script allows you to copy files or directories locally or between a local machine and a remote cluster using the Secure Copy Protocol (SCP). It also performs an integrity check using MD5 checksums to ensure the successful transfer of data.

Usage

$ ./copy_cluster_copy.sh [SOURCE] [DESTINATION]

Arguments

• SOURCE: The path to the source file or directory. It can be a local path or a remote path in the format user@server:/path/to/source.
• DESTINATION: The path to the destination directory. It can be a local path or a remote path in the format user@server:/path/to/destination.

Functionality

The script performs the following actions based on the provided arguments:

1. Extracts the server and source paths.
2. Transfers the source directory using SCP.
3. Calculates the MD5 checksum of server and local directories.
4. Compares the server and local MD5 checksums and displays the results.

Example

Note: if you just downloaded copy_cluster_copy on your machine, make it executable first

$ chmod +x copy_cluster_copy.sh

Local to Cluster Transfer

$ ./copy_cluster_copy.sh dir username@server:/path/to/remote/.

Cluster to Local Transfer

$ ./copy_cluster_copy.sh username@server:/path/to/remote/dir . 

Please note that the script requires SSH and SCP to be properly configured for the remote server to enable successful transfers.
