The book covers topics related to the Linux operating system and operating systems in general. It chronicles the history of Unix and how it led to the creation of Linux. The book provides samples of code written in C, and learning exercises at the end of chapters.
On Linux systems using ELF-format executable files, the dynamic linker that manages the use of dynamic libraries is known as ld-linux.so. If the system is set up for the user to compile software themselves, header files will also be included to describe the programming interface of installed libraries. Besides the most commonly used software ...
Systems programming, or system programming, is the activity of programming [1] computer system software.The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and ...
systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.
The book illustrates UNIX application programming in the C programming language. The first edition of the book was published by Addison-Wesley in 1992. It covered programming for the two popular families of the Unix operating system, the Berkeley Software Distribution (in particular 4.3 BSD and 386BSD) and AT&T's UNIX System V (particularly SVR4).
Linux From Scratch (LFS) is a type of a Linux installation and the name of a book written by Gerard Beekmans, and as of May 2021, mainly maintained by Bruce Dubbs. The book gives readers instructions on how to build a Linux system from source. The book is available freely from the Linux From Scratch site. [1]
The book closes with a tutorial on making a programming language parser with yacc and how to use troff with ms and mm to format documents, the preprocessors tbl, eqn, and pic, and making man pages with the man macro set. The appendices cover the ed editor and the abovementioned programming language, named hoc, which stands for "high-order ...
Pseudoterminals as they are used by script unix command that records user's input for replaying it later.. In some operating systems, including Unix-like systems, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-device endpoints (files) which establish asynchronous, bidirectional communication channel (with two ports) between two or more processes.
