About Git Bash
Git Bash is a program that offers an emulation layer for the Git command line interface.
Popular default shells for Linux and macOS are bash. On a Windows operating system, Git Bash is a package that installs bash together with a few standard Linux utilities.
Git Bash has the same operations as a standard Bash experience.
Git Bash is packaged with additional commands that can be found in the /usr/bin directory. Git Bash can actually provide a fairly robust shell experience on Windows.
