Cygwin 3.5.5 is a robust software package that enables users to run a Unix-like environment on Windows. It achieves this through two main components: a dynamic-link library (DLL).
Cygwin 3.5.5 Description
That acts as a POSIX API compatibility layer and a collection of software tools and applications that provide a Unix-like interface and functionality. To use Cygwin, users typically run the “setup” program which downloads and installs the necessary packages from online repositories. The setup program also functions as a package manager for updating and managing installed software.
If you want to use Linux applications on your Windows computer, as well as if you want to build a Linux server, Cygwin is a good solution that offers several options. The Mintty terminal emulator is the default command-line interface for interacting with the environment. The Cygwin installation directory layout mimics the root file system of Unix-like systems with directories such as /bin, /home, /etc, /usr, and var.
Features For Cygwin 3.5.5
Compatibility Layer:
- The core of Cygwin is its dynamic-link library that provides a Unix-style environment on Windows. This includes a POSIX API layer which allows Unix-based applications to run on Windows without modification
- Extensive Software Collection:
- Cygwin includes a wide range of Unix tools and applications, such as the GNU Bash shell, and supports package management for installing additional software. The base installation provides essential tools, and users can download additional packages as needed
- File System Integration:
- Cygwin can mount Windows paths as filesystems in the Unix file space, supporting both binary and text modes to handle the different newline conventions of Unix (LF)
- Process Management:
- Cygwin implements the Unix fork system call, which is complex to map onto the Windows API. The implementation includes workarounds for various Windows limitations, ensuring that Unix-style process creation and management can be performed effectively​
- Terminal Emulation:
- The default interface is the Bash shell, but Cygwin also supports other terminal emulators like Mintty and Xterm. It provides a console driver to emulate Unix-style terminals within the Windows console.
