The article discusses how to use `dd skip=` for `mmap`-like file reading in Linux. It explains `mmap` as a technique mapping files into memory for efficient access, contrasting it with `dd`, which doesn't use `mmap` but can mimic aspects by skipping to specific file parts, useful in large data sets. An example command provided is `dd if=largefile.bin of=segment.bin bs=1M skip=10 count=5`, demonstrating how to access file segments directly.
