- Libro 7 de 23: Learn Programming in 14 Days
Fourteen days of drills that turn shell scripting into something you can trust on a machine you cannot watch.
This is a book of problems. Every rule is stated in as few words as it can be, shown working in a short script with its real captured output, and then handed back as drills. Nothing is asserted that is not also demonstrated: every listing in the book was run under GNU Bash 5.3.15 on Linux, and every printed result was captured from that run.
The programming problems build one real tool across the fourteen days. It is called sentry, a host audit command. It begins on Day 1 as a script that refuses to run half-broken and gains, day by day, arguments that survive a space, settings with defaults, named checks chosen by option, tallies in arrays, log reading that loses no character, file discovery that survives every legal filename, a formatted report, checks that run in parallel behind a lock, and finally a dry run, a self-test, a log and an installable command.
The shell is not a passenger here. Quoting decides whether a filename with a space is one argument or two. Strict mode decides whether a failed command stops the script or is ignored. A subshell decides whether a counter survives the loop that filled it. Every one of those decisions is shown as a measurement rather than an opinion, and the book prints both outcomes.
The two weeks run in two movements. Days 1 to 7 cover the language: the execution model and strict mode, quoting and expansions, parameter expansion, tests and control flow, arrays, functions and scope, and reading input safely. Days 8 to 14 cover the machine: processes, pipelines and exit status, globs and awkward filenames, traps and cleanup, text processing inside the shell, concurrency and locking, the failure modes a defensive script must survive, and packaging a script an operator can run at three in the morning.
Every chapter has the same shape. Numbered sections state the rules. Twenty worked examples show each rule running, each with a complete script, its real output, a figure and a short explanation. Then a fixed ladder of five problem sets: review questions, worked problems with full solutions, worked programming problems, and unassisted practice problems in both written and programming form. The review answers are at the end of the chapter; the practice problems have no answers anywhere, by design.

Descripción de la tienda
We first started out as “The Paperback Exchange,” a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become “PBShop.” This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.…
