bat/cmd file help

    Howdy, need to write a bat/cmd file and need a little help. It has to do a simple function that after crawling through the web, seems not so simple.

    I have a folder on a server that contains sub-folders. Basically i need to write a script that runs as a scheduled task (every week/month, etc). And the script has to keep the sub-folders less than a month old, and delete everything else.

    In other words the folder on the server fills up on an irregular basis (could be 3 new sub folders a day, could be none) and we need to keep all folders for the past month and delete the rest...

    Messing about with dates through dos is worknig out to be a right b!tch...

    Any help appreciated

    One way is to use the XCOPY /D /D:ddmmyy command - you copy all files less than a month old to a new folder and delete the rest and them copy them back

    pharsing the date to get a month and decrementing it is messy but can be done with FOR loops.

    Would it help any to install Perl or PHP on the server and use a PHP/Perl script to do this?

    Perl is a whizz with this kind of thing.

    Could even try python scripting. I had to use python recently in college for various file operations and I found it quite nice. The website has a great help section too.

    I'm not sure how consistant syntax has been over time in Python / Perl / PHP

    but the XCOPY command is all over the place with four main flavours :(
    * Dos/Dos Mode in 9x no /D
    * Win 9x command prompt /D
    * NT 3/4
    * 2K/XP (exclude , needing /Y to overwrite etc.)
    there are subtle differences too within the flavours...

    why make it so complicated, install cygwin, and bash script it! a couple of greps an xargs and rm -rf and you're sorted, more details and i'll write it for you, and then you can cron it on the server for automatic execution
