问题 I have a Java application which I call from the command prompt like this: C:\Mydir> C:\dir2\my.exe When I call this application I would like to retrieve at the same time the path "C:\MyDir", i.e. the active directory from where my exe is called in the prompt and not "C:\dir2\" where the exe is found.

问题 So I know this question have been asked a lot , but I don't find any suitable answers. I'm looking to display the name of the current git rev in my prompt, but in a pretty way : if I'm on a branch, I want the name of the branch; if it's not a branch, I'd like the relative name (ie master~2 ) in my prompt.

For example: if I run python_process1.py and python_process2.py and would like to kill the .exe associated with just python
