Command line to delete every file older than 30 days

Posted by shawson in Batch Scripting on February 19th, 2010

I found a new command line directive i’d never heard of today, along with a brilliant example of it’s use- once you have changed your working directory, running this will remove any files or folders older than 30 days;

FORFILES /D -30 /C "CMD /C IF @isdir==FALSE (echo Deleting File @file) & (ATTRIB -H @file) & (DEL /F /Q @file) ELSE (echo Deleting Directory @file) & (ATTRIB -H @FILE) & (RD /S /Q @FILE)"

As an example, I’ve since used this to iterate over a bunch of folders, deleting any files over 30 days;

d:
for /f "delims=|" %%f in ('dir /b D:\_SQL_Backup\') DO (
  cd \_SQL_Backup
  cd %%f
  FORFILES /D -14 /C "CMD /C IF @isdir==FALSE (echo Deleting File @file) & (ATTRIB -H @file) & (DEL /F /Q @file)"
)

Umbraco Installation – folder permissions setup

Posted by shawson in Batch Scripting, Umbraco on November 30th, 2009

Just a real quick batch script i knocked up which sets the appropriate permissions to the various folders in the root of a fresh umbraco install- just drop this into a batch file, and run it from the root of your umbraco install;

REM 2009.10.22 SY - Set permissions- user/ folders from "Install Umbraco 4 on Windows Vista" guide
icacls app_code /grant "Network Service":(OI)(CI)(F)
icacls bin /grant "Network Service":(OI)(CI)(F)
icacls config /grant "Network Service":(OI)(CI)(F)
icacls css /grant "Network Service":(OI)(CI)(F)
icacls data /grant "Network Service":(OI)(CI)(F)
icacls masterpages /grant "Network Service":(OI)(CI)(F)
icacls media /grant "Network Service":(OI)(CI)(F)
icacls python /grant "Network Service":(OI)(CI)(F)
icacls scripts /grant "Network Service":(OI)(CI)(F)
icacls umbraco /grant "Network Service":(OI)(CI)(F)
icacls usercontrols /grant "Network Service":(OI)(CI)(F)
icacls xslt /grant "Network Service":(OI)(CI)(F)

Command line Batch File to Remove Direcories, using a Wild Card!

Posted by shawson in Batch Scripting, Command Line on October 28th, 2009

We have a bunch of web services which log details of requests that come in, in folders named using the current date- in the format YYYY-MM-DDD-HH-MM-SS. I wanted to produce a simple cleanup batch file which we could run every month to bin all logs for transactions which happened 3 months ago- using the dos commands which exist on Windows Server 2003.

The dos “del” command allows you to delete using wild cards – so for example “dev 2009-07-*” would erase any files starting with “2009-07-”; However this doesn’t work with folders- so it fell to the rd (remove directory) command- but this doesn’t support wild cards (I’m assuming for safety- to stop you permanently erasing 100’s of folders and their contents accidently- remember there’s no recycle bin when you delete from the command line!).

To get around this I created a simple Batch file which accepted a wildcard as a parameter, then removes all those folders at the current level (it wont check recursivly). Just in case this is of use to anyone else, here’s the code;

REM - performs a remove directory, with wildcard matching - example ; rd-wildcard 2007-*
dir %1 /b >loglist.txt
setlocal enabledelayedexpansion
for /f %%a in (./loglist.txt) do (
	rd /s /q %%a
)
del /q loglist.txt
endlocal
