Description in English: Although most users think of Shell as a mere interactive command interpreter, the reality is that it is a programming language in which each statement is executed as a command.The Shell is the interface that allows the user to interact with the system: it collects the orders, processes them and generates the corresponding output, isolating the user from the system kernel throughout the process, which gives GNU / Linux environments a great deal of security. There are different Shell languages, but this work focuses on Bash, since it is the most widely used command interpreter on GNU / Linux systems and includes a complete structured programming language and a wide variety of internal functions.The objective of this work is to introduce the reader in a theoretical-practical way to Shell programming, from the most basic aspects of it to more complex elements, which allow it to work safely and efficiently with GNU / Linux environments, from personal computers to servers. For this reason, multiple examples are presented, which increase in complexity as the necessary knowledge is acquired, while the reader is challenged to apply the knowledge acquired to solve different proposed problems, all of them of real practical nature.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/1/68/165/766/168165766X_b.jpg", "price_data" : { "retail_price" : "31.95", "online_price" : "31.95", "our_price" : "31.95", "club_price" : "31.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
