  • Command line semaphore utility

    - by compie
    I want to write a command line utility that can be used to synchronize the execution off programs in different consoles. Console A: $ first_program && semaphore -signal Console B: $ semaphore -wait && second_program The first program takes a long take to complete. The second program can only start when the first program has finished. Which synchronization object do I need to implement this (in Python)?

  • Exit to command line in Python

    - by fuenfundachtzig
    I have a script that I want to exit early under some condition: if not "id" in dir(): print "id not set, cannot continue" # exit here! # otherwise continue with the rest of the script... print "alright..." [ more code ] I run this script using execfile("foo.py") from the Python interactive prompt and I would like the script to exit going back to the command line. How do I do this? If I use sys.exit(), the Python interpreter exits completely.

  • Python run command line (time)

    - by pns
    Hi, I want to run the 'time' unix command from a Python script, to time the execution of a non Python app. I would use the os.system method. Is there any way to save the output of this in Python? My goal is to run the app several times, save their execution times and then do some statistics on them. Thank You

  • WPF: ContextMenu item bound to a Command is enabled only after invoking the command from another so

    - by Brad
    I have a ContextMenu whose items are all bound to commands and enable\disable correctly after ANY Command is invoked from another source but prior to, they are all disabled. So if I run the app, all the MenuItems are disabled but if I invoke any of the bound commands from another source (buttons, for instance) they become synchronized with the CanExecute code. I have no idea how to debug this. Any thought would be helpful!?!

  • Reading all compile errors in Windows command-line?

    - by ArdillaRoja
    Noob question, apologies. I'm compiling Java in Windows Vista's command-line and have so many syntax errors that some are being pushed off the top (a lot of 'class, interface or enum expected' errors which leads me to believe it's an obvious syntax mistake early on in the code that I can't spot). Does anyone know how I could get it to display those first errors? Thanks in advance for the help.

  • Automatically open files given as command line arguments in Python

    - by mk
    I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?
