The command "7zr x ${path-to-archive-7z} -so" is used to extract the contents of a 7z archive file and send the output to the standard output (STDOUT).

Here's a breakdown of the command:

• "7zr" is the command-line utility for the 7-Zip file compression/decompression program.
• "x" is the command option for extracting files from an archive.
• "${path-to-archive-7z}" is a placeholder for the actual path to the 7z archive file. You need to replace it with the path to your specific 7z file.
• "-so" is an option that directs the extraction output to the standard output instead of saving it to the filesystem. It stands for "stdout" or "standard output."

By using this command, the contents of the 7z archive file will be extracted and displayed on the terminal or command prompt screen rather than being saved as separate files on the filesystem.
