Linux. Wiersz poleceń i skrypty powłoki. Biblia. Wydanie IV

Christine Bresnahan, Richard Blum

Odkąd systemy linuksowe mają atrakcyjne interfejsy graficzne, wielu administratorów wykonuje swoje zadania za pomocą myszy. Wiersz poleceń jest o wiele trudniejszym interfejsem, ten sposób pracy jednak pozwala na wykorzystanie pełnego potencjału Linuksa i uzyskanie dostępu do funkcji, które w inny sposób byłyby nieosiągalne. Umiejętność pisania skryptów wiersza poleceń i powłoki Linuksa wciąż jest niezwykle ważna dla każdego administratora, któremu zależy na efektywnym działaniu systemu. Ta książka, podobnie jak inne z serii "Biblia", zawiera zarówno niezbędne teoretyczne informacje, jak i mnóstwo praktycznych wskazówek i instrukcji, dzięki czemu jest znakomitą pomocą w nauce pisania skryptów dla Linuksa. Pokazano tu, kiedy efektywniej jest używać interfejsu graficznego, a kiedy lepiej sięgnąć do wiersza poleceń. Opisano elementy systemu Linux i przedstawiono podstawowe informacje o powłoce, a także o pracy w wierszu poleceń. Zaprezentowano techniki przetwarzania danych użytkownika w skryptach, pracę z systemami plików, wreszcie - sposoby instalacji i aktualizacji oprogramowania. Sporo miejsca poświęcono pracy z wyrażeniami regularnymi i zaawansowanym metodom manipulacji danymi, pokazano też, jak zmodyfikować skrypty powłoki, aby działały w innych powłokach Linuksa. Najciekawsze zagadnienia: tworzenie praktycznych skryptów i narzędzi skryptowych i zarządzanie nimi alternatywne powłoki, takie jak dash i zsh edytory gawk i sed podstawowe i rozszerzone wyrażenia regularne tworzenie skryptów powłoki dla pulpitów graficznych w środowiskach KDE i GNOME pisanie podstawowych i zaawansowanych funkcji Wiersz poleceń: oto pełny potencjał Linuksa!

Mastering Assembly Programming. From instruction set to kernel module with Intel processor

Alexey Lyashko

The Assembly language is the lowest level human readable programming language on any platform. Knowing the way things are on the Assembly level will help developers design their code in a much more elegant and efficient way. It may be produced by compiling source code from a high-level programming language (such as C/C++) but can also be written from scratch. Assembly code can be converted to machine code using an assembler.The first section of the book starts with setting up the development environment on Windows and Linux, mentioning most common toolchains. The reader is led through the basic structure of CPU and memory, and is presented the most important Assembly instructions through examples for both Windows and Linux, 32 and 64 bits. Then the reader would understand how high level languages are translated into Assembly and then compiled into object code. Finally we will cover patching existing code, either legacy code without sources or a running code in same or remote process.
