Filtering log files on Windows 7

Note: this is just a reminder about Windows analogues of grep - find and findstr.

Being inspired by this article: http://habrahabr.ru/post/71568/
now leaving some how-to's when working with large log files, containing messages from many processes.

How to get messages from interval [2014-09-22, 2014-09-26]

C:\logs> type file.log  | findstr /r /C:"2014-09-2[2-6]"
2014-09-22 16:40:22    [INFO] Closing Session: 
2014-09-22 16:40:35    [WARNING] Error: No IC output on selected net (i.e., no driver).Stopping.

Note that  /r stands for regular expressions. But regexps are limited in findstr, only [class] or [a-b] is allowed. See http://technet.microsoft.com/ru-ru/library/bb490907.aspx for reference.

Compiling .cpp files in FAR by pressing Enter

%comspec% /k ""C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat"" x86
