command-line

问题 In my old python script, I use the following code to show the result for Windows cmd command: print(os.popen("dir c:\\").read()) As the python 2.7 document said os.popen is obsolete and subprocess is recommended. I follow the documentation as: result = subprocess.Popen("dir c:\\").stdout And I got error message: WindowsError: [Error 2] The system cannot find the file specified Can you tell me the correct way to use the subprocess module? 回答1: You should use call subprocess.Popen with shell

问题 Using command-line ghostscript, is it possible to remove duplicate embedded objects (images) in the PDF and replace them with a single instance? I have a 200+ pages PDF with a background image and some smaller logos on each page. The file is very large, because the very same background image and logo binaries are embedded in each individual page, instead of being embedded once and then referenced on each page. I am not the creator of the PDF so I can not solve the problem at it's source. (I

问题 I have been having an issue recently with Visual Studio 2015 and the only workaround I can find is opening up the developer command line and executing "devenv.exe /resetuserdata" That solves the problem (until the next windows update typically brings it back). I have been trying to troubleshoot this for a while so I can actually determine the root cause but one big issue is that I cannot find any msdn documentation about this command "devenv.exe /resetuserdata" So that is essentially my

问题 I wrote a C command line tool which uses GLUT to visualize a genetic algorithm and I want to distribute it in a Mac OS X .app Bundle. How do I do that? Are there any helper tools available for this? Thank you very much! Thomas Edit: Thank you very much for your help, I didn't think of it being that easy! 回答1: Create new xcode project, with "application" template. Add your source code to that project, compile and... You have app bundle. You need only to deploy it (add frameworks). Thats all.

问题 I'm trying to set the background and foreground colors of the Windows command line console by using GetConsoleScreenBufferInfoEx and SetConsoleScreenBufferInfoEx . I'm doing it in Python, by using wintypes, and sofar it works. But there's something odd happening: the window shrinks a little at every call. This is how the calling code looks like: def GetConsoleScreenBufferInfoEx(handle): csbi = CONSOLE_SCREEN_BUFFER_INFOEX() # a structure csbi.cbSize = 96 # needs to be set success =
