Structure and Interpretation of Computer Programs (SICP) is a textbook aiming to teach the principles of computer programming, such as abstraction in programming, metalinguistic abstraction, recursion, interpreters, and modular programming. It is widely considered a classic text in computer science. It was first published in 1984 by MIT Press and written by Massachusetts Institute of Technology (MIT) professors Harold Abelson and Gerald Jay Sussman, with Julie Sussman... Before SICP, the introductory courses were almost always filled with learning the details of some programming language, while the SICP focused on finding general patterns from specific problems and building software tools that embody each pattern.

How to set chmod for a folder and all of its subfolders and files in Linux Ubuntu Terminal?

Ever need to set permissions recursively on a directory? You could just make do everything all-in-one with something like:

chmod -R 644 path/to/blah

That might cover all the files fine with -rw-r--r--. But don't do that, what about any subdirectories? Use find by type:

find path/to/blah -type d -exec chmod 755 {} \; find path/to/blah -type f -exec chmod 644 {} \;
