Git Bash doesn't see my PATH

Got it. As a Windows user, I'm used to type executable names without extensions. In my case, I wanted to execute a file called cup.bat. In a Windows shell, typing cup would be enough. Bash doesn't work this way, it wants the full name. Typing cup.bat solved the problem. (I wasn't able to run the file though, since apparently bash couldn't understand its contents)

One more reason to switch to posh-git..

Thanks @Tom for pointing me to the right direction.

Maybe bash doesn't see your Windows path. Type env|grep PATH in bash to confirm what path it sees.

Following @Daniel's comment and thanks to @Tom's answer, I found out that Git bash was indeed using the PATH but not the latest paths I recently installed. To work around this problem, I added a file in my home (windows) directory named:

.bashrc

and the content as follow:

PATH=$PATH:/c/Go/bin

because I was installing Go and this path contained the executable go.exe Now Git bash was able to recognize the command:

go

Perhaps just a system reboot would have been enough in my case, but I'm happy that this solution work in any case.
