executable

I'm looking for something like $ stack whereis hasktags where whereis acts more or less like UNIX whereis command. hasktags is to be run like this: $ stack exec -- hasktags stack exec -- whereis hasktags will do. stack exec -- whereis yourprogramname works for me on a Linux box, but I have to use stack exec -- which yourprogramname on Mac OS X. ( which also works on Linux, of course.) Note that neither of these are useful for automating deployments when the executable name is the same as one on the build machine -- not likely, but not impossible. 来源： https://stackoverflow.com/questions

In a shell, what is the difference between? . executable and ./executable In the first one, the dot a shortcut for source right? So is there a difference between ./executable and source executable ? is there a difference between ./executable and source executable? basic difference is, ./foo.sh - foo.sh will be executed in a sub-shell source foo.sh - foo.sh will be executed in current shell some example could help to explain the difference: let's say we have foo.sh : #!/bin/bash VAR=100 source it: $ source foo.sh $ echo $VAR 100 if you : ./foo.sh $ echo $VAR [empty] another example, bar.sh #!

How can you find out if an executable is running on Windows given the process name, e.g. program.exe? The C++ standard library has no such support. You need an operating system API to do this. If this is Windows then you'd use CreateToolhelp32Snapshot(), followed by Process32First and Process32Next to iterate the running processes. Beware of the inevitable race condition, the process could have exited by the time you found it. I just created one using Hans suggestion. Works like a champ! Oh and here is the basic code. Please you will have to add CStrings sAppPath and sAppName. StartProcess is

I have an application in a python script my_app.py and want to make a standalone executable out of it on a MacOS (10.14). Following the video-tutorial here , I entered sequentially the following commmands: pip install virtualenv virtualenv venv --system-site-packages source venv/bin/activate pip install py2app cd /path/to/my_app.py python setup.py py2app -A with the following setup.py file: from setuptools import setup APP = ["my_app.py"] DATA_FILES = [] OPTIONS = { "argv_emulation": True, "packages": ["certifi"], } setup( app = APP, data_files = DATA_FILES, options = {"py2app": OPTIONS},

I have a managed DLL (written in C++/CLI) that contains a class used by a C# executable. In the constructor of the class, I need to get access to the full path of the executable referencing the DLL. In the actual app I know I can use the Application object to do this, but how can I do it from a managed DLL? Assembly.GetCallingAssembly() or Assembly.GetExecutingAssembly() or Assembly.GetEntryAssembly() Depending on your need. Then use Location or CodeBase property (I never remember which one). Brian Stewart @leppie: Thanks - that was the pointer I needed. For future reference, in C++/CLI this
