How to run .sh on Windows Command Prompt?

How can I run .sh on Windows 7 Command Prompt? I always get this error when I try to run this line in it,

app/build/build.sh

error,

'app' is not recognized...

or,

bash app/build/build.sh

error,

'bash' is not recognized...

Any ideas what have I missed?

Here the screen grab, enter image description here

Solution

The error message indicates that you have not installed bash, or it is not in your PATH.

The top Google hit is http://win-bash.sourceforge.net/ but you also need to understand that most Bash scripts expect a Unix-like environment; so just installing Bash is probably unlikely to allow you to run a script you found on the net, unless it was specifically designed for this particular usage scenario. The usual solution to that is https://www.cygwin.com/ but there are many possible alternatives, depending on what exactly it is that you want to accomplish.

If Windows is not central to your usage scenario, installing a free OS (perhaps virtualized) might be the simplest way forward.

The second error message is due to the fact that Windows nominally accepts forward slash as a directory separator, but in this context, it is being interpreted as a switch separator. In other words, Windows parses your command line as app /build /build.sh (or, to paraphrase with Unix option conventions, app --build --build.sh). You could try app\build\build.sh but it is unlikely to work, because of the circumstances outlined above.
