create batch file to copy folder contents with dynamic name

阅读更多关于 create batch file to copy folder contents with dynamic name

I am absolutely brand new to any kind of development but need a batch job to copy a file from one folder to another. The problem is that the source folder is dynamically named. The folder name will contain the current date and a suffix number (eg. "TestRun_20141106_13") - so I will never be able to determine the 'latest' version of the folder before running the batch / copy job. Can anyone help please? I know this will be easy for someone but as I said, I am a complete noob!! Thanks in advance. Jamie LoganMurphy Yes, I havent been doing .bat for that long either, but i think i can help! Here

configure the left and right mac 'command' keys differently?

阅读更多关于 configure the left and right mac 'command' keys differently?

I'm wandering if I can set the right mac 'command' to act like the ctrl key, but keep the default functionality of the left 'command' key. Thanks. There is a really awesome application called Ukelele (free) that is, unfortunately, unable to distinguish between left and right command keys. However, there is an even better application I recently found called "ControllerMate" that lets you do exactly what you want. You can find it here: http://www.orderedbytes.com/controllermate/ If you have questions about how to use it... well that's a totally different topic. It took me literally 30 seconds to
