Really love your comment, so much that I wanted to check out the books you mentioned. After searching z-lib for "The UNIX Programming Environment", all I found was a janky and grainy PDF. Then I searched archive.org and discovered this high fidelity PDF version: https://archive.org/details/UnixProgrammingEnviornment https://archive.org/details/UnixProgrammingEnviornment Note: Sadly, the EPUB version is 10x larger (370MB) and is corrupted, not able to be opened / viewed.
