recursion - Using Perl, how can I rename files in all subdirectories of a drive? -

-

itemprop = "text">

I can rename all the files on the drive with the .wma and .wmv extensions. In directory structure?

The examples given in the documentation are very self-explanatory and you will find most of the methods there. When you have an attempt, update the question with more information.

If this is a learning curve, then you will learn better before trying to do yourself.

Update:

Assuming that you have to do this and have a chance to keep in mind that various solutions were posted I am posting how I could have done this. Note that I choose to ignore files like ".wmv": My regeses need to come before the dot. 

  #! Use / usr / bin / perl strict; Use warnings; File :: Use Search; Mine ($ dir) = @ARGV; Find (& amp; mc, $ dir); The Deputy wanted {until the return -f; Unless that / ^ (. +) \ .wm [av] $ / i; My $ new = "$ 1.txt"; Rename $ _ = & gt; $ New or alert "'$ _' = & gt; '$ new' failed: $! \ N"; Return; } __END__

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
