Merge_dirs_v2.pl:

Here's a detailed step-by-step explanation of the Perl program:

1. Shebang Line and Pragmas:

#!/usr/bin/perl: Tells the operating system to use Perl to execute the script. use strict;: Enforces stricter variable and code syntax for better error checking. use warnings;: Enables warnings to catch potential issues during execution. 2. Input and Validation:

Prompts the user to enter the source and destination directory names. Stores the input in variables $source_dir and $destination_dir. Uses -d to check if both directories exist and terminates with an error message if either is missing. 3. Initialization:

Sets $moved_files to 0 to count the number of files moved. Sets $total_data_transferred to 0 to track the total data moved. 4. Processing Files:

Opens the source directory using opendir and assigns a directory handle $source_dh. Loops through each filename in the source directory using readdir. Skips the current and parent directory entries (. and ..). Constructs full file paths for the source and destination files. Skips files if they already exist in the destination to avoid overwriting. Checks if the source file is a symbolic link (-l) and skips it, printing a message. For regular files: Gets the file size using -s. Moves the file using rename or terminates with an error if unsuccessful. Increments $moved_files and $total_data_transferred. Prints a message indicating the successful move and file size. Closes the source directory handle using closedir. 5. Telemetry and Optional Removal:

Prints a summary of the merged files and total data transferred. Optionally removes the source directory if it's empty (by uncommenting the rmdir line). Prints a message indicating completion.
