As a command processor, Bash operates within a text window where users input commands to execute various tasks. It also supports the execution of commands from files, known as shell scripts, facilitating automation. In keeping with Unix shell conventions, Bash incorporates a rich set of features.
The Preboot Execution Environment (PXE) was introduced as part of the Wired for Management [ 2] framework by Intel and is described in the specification published by Intel and SystemSoft. PXE version 2.0 was released in December 1998, and the update 2.1 was made public in September 1999. [ 3] The PXE environment makes use of several standard ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
Runlevel. A runlevel is a mode of operation in the computer operating systems that implements Unix System V -style initialization. Conventionally, seven runlevels exist, numbered from zero to six. S is sometimes used as a synonym for one of the levels.
Unix shell. A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. [2]
Execution of process creation system call by a running process. A user request to create a new process. Initiation of a batch job. When an operating system is booted, typically several processes are created. Some of these are foreground processes, that interact with a (human) user and perform work for them.
The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. [ 1] Its most notable applications are remote login and command-line execution. SSH was designed for Unix-like operating systems as a replacement for Telnet and unsecured remote Unix shell protocols, such as ...
Thread (computing) In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [ 1] In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via ...
