Executable and Linkable Format. 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 ...
Executable files can be hand-coded in machine language, although it is far more convenient to develop software as source code in a high-level language that can be easily understood by humans. In some cases, source code might be specified in assembly language instead, which remains human-readable while being closely associated with machine code ...
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 ...
COFF. The Portable Executable ( PE) format is a file format for executables, object code, DLLs and others used in 32-bit and 64-bit versions of Windows operating systems, and in UEFI environments. [ 2] The PE format is a data structure that encapsulates the information necessary for the Windows OS loader to manage the wrapped executable code.
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.
Comparison of executable file formats. This is a comparison of binary executable file formats which, once loaded by a suitable executable loader, can be directly executed by the CPU rather than being interpreted by software. In addition to the binary application code, the executables may contain headers and tables with relocation and fixup ...
Shellcode. In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability. It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. [ 1] The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the ...
