In this article, we shall discuss How to determine Cygwin version. Considering many software packages or tools may require a specific version of Cygwin or may not be compatible with older versions. Knowing your version helps you ensure compatibility with the software you intend to use. Please see How to install Kerberos packages with Cygwin on Windows, how to determine GPO from GUID or Name, and How to create a Dev Drive on Windows 11.

Cygwin consists of a Unix system call emulation library, cygwin1.dll, together with a vast set of GNU and other free software applications organized into a large number of optional packages.
Among these packages are high-quality compilers and other software development tools, an X11 server. A complete X11 development toolkit, GNU emacs, TeX and LaTeX, OpenSSH (client and server). And much more, including everything needed to compile and use PhysioToolkit software under MS-Windows.

Determine Cygwin version
To run such software using Cygwin, it must be compiled from its sources. Cygwin provides all the components needed to do this in most cases.
Nonetheless, using Cygwin, most POSIX-compliant software, including X11 applications, can easily be ported to MS Windows.
Consequently, Here are the various commands that can be used to determine the various versions of Cygwin.
cygcheck -c cygwin$ uname –r1. Using the “cygcheck -c Cygwin” command finds the version of the check the version of the cygwin package
2. Using the ‘uname –r” used to find the version of the kernel on a Linux system
