What is win-bash?
win-bash is a Windows port of the famous GNU bash (see GNU Bash homepage).
The goal of the win-bash project is to finish the port to Windows and provide a full functional bash.exe binary for windows nt and derived systems. win-bash can be used as a input shell as well as an interpreter to run un*x shell scripts
The project is no longer developed since 2016. Last version, 1.1, released in March 2011, can be still downloaded from SourceForge.
