I am using the latest version of Git in bash and I am trying to execute basic commands e.g php. I have set the environment variable to C:\wamp\bin\php\php5.5.12 in Path.
However when I execute these basic commands nothing comes up, not even sh.exe: command not found. If you have any suggestions please let me know.

PATHenvironment variable looks like from inside mingw?. You might want to launch it again after having modify the path from your control panel
