Answer by Arnaldo C for How to add more commands to Git Bash?

If you are using msysgit a simple option is to just install MinGW and then add the MINGW path to the .bashrc file you are using for your Git installation:

    PATH=$PATH:/MINGW/msys/1.0/bin

...where MINGW is where you installed MinGW

That way you can use the MinGW tools directly from your Git bash installation, and if you need another bash tool you can just install it to MinGW.
