shc takes a shell script which is specified on the command line by the -f option and produces a C source code of the script with added encryption. The generated source code is then compiled and linked to produce a binary executable. It is a two step process where, first, it creates a filename.x.c file of the shell script file filename.
GNU Make (short gmake) is the standard implementation of Make for Linux and macOS. [16] It provides several extensions over the original Make, such as conditionals. It also provides many built-in functions which can be used to eliminate the need for shell-scripting in the makefile rules as well as to manipulate the variables set and used in the ...
The script can be and originally was hand-coded. Today, multiple tools are available for generating a configure script based on special configuration files. One commonly used tool is Autotools which generates a Bash script. Obtaining a software package as source code and compiling it locally is a common scenario on Unix and Unix-like ...
Called meta-build tools, these generate configuration files for other build tools such as those listed above.. CMake – Cross-platform build tool for configuring platform-specific builds; very popoular; integrated with IDEs such as Qt Creator, [1] KDevelop and GNOME Builder [2]
Editing a FreeBSD shell script for configuring ipfirewall. 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 command languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing ...
UPX uses a data compression algorithm called UCL, [5] which is an open-source implementation of portions of the proprietary NRV (Not Really Vanished) [6] algorithm. [2]UCL has been designed to be simple enough that a decompressor can be implemented in just a few hundred bytes of code.
The Bourne shell (sh) is a shell command-line interpreter for computer operating systems.It first appeared on Version 7 Unix, as its default shell. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users.
BusyBox is a software suite that provides several Unix utilities in a single executable file. It runs in a variety of POSIX environments such as Linux, Android, [8] and FreeBSD, [9] although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems ...
