    reading log files as they're being appended

    I have a program that is constantly writing to a log file. At the moment I check on it by opening the log file in notepad, closing it and reopening it. Then I see that OSX has a really groovy console utility for viewing logs as they're being written and I though there has got to be something like that for windows. Any suggestions?

    At first open, read the file (perhaps start from the back and read only X lines from the back)
    Then, when you have found the last line, you try to read some from the file. If you get EOF immediately, sleep for x ms, then try again.

    You could possibly use the Windows API that signals changes to files, but I doubt it's really necessary. See this, if you are interested: http://msdn.microsoft.com/en-us/libr...17(VS.85).aspx

    baretail looks good. It'd be nice if it were free, but oh well.
