Paperback. Etat : new. Paperback. 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.Your 14-day pathWeek 1 - the languageDay 1 - The Shell, the Script and Strict ModeDay 2 - Words, Quoting and the Order of ExpansionsDay 3 - Parameters and Parameter ExpansionDay 4 - Tests, Conditions and Control FlowDay 5 - Arrays and Associative ArraysDay 6 - Functions, Scope and Return ValuesDay 7 - Reading Input with read, IFS and File DescriptorsWeek 2 - the machineDay 8 - Processes, Pipelines and Exit StatusDay 9 - Files, Globs and Awkward NamesDay 10 - Traps, Signals and CleanupDay 11 - Text Processing inside the ShellDay 12 - Concurrency, Jobs, wait and LocksDay 13 - The Failure Modes of a Shell ScriptDay 14 - Packaging a Script for OperationsWho it's forSystem administrators who write the scripts a fleet depends on.
