R.tar.gz Access

In his post, Russ Cox demonstrates how to create a file that, when unpacked, contains a file identical to itself. This creates an infinite loop of extraction:

: It is the standard format for the source code of the R programming language (e.g., R-4.3.1.tar.gz ) found on CRAN . R.tar.gz

The phrase most likely refers to a famous blog post by Russ Cox titled "Zip Files All The Way Down," which explores the concept of a self-reproducing archive, or a decompression quine . The Recursive Archive Concept In his post, Russ Cox demonstrates how to

Outside of this specific "quine" experiment, R.tar.gz is a common filename in other technical areas: The Recursive Archive Concept Outside of this specific

: It is a frequent naming convention for automated server backups (e.g., backup.R.tar.gz ) used in shell scripts to save databases or system configurations.

: The archive uses the properties of the DEFLATE algorithm and the way zip/tar headers work to point back to the beginning of the file, essentially creating a loop. Common Technical Contexts
