[APP] Tasker: Share your setup

There are only a few actions to explain in more detail:

The task [B]NandroidFiles[/B] deletes the Nandroid backups from two days before. I set this as two days so not to use too much storage space and to make sure there was a spare backup in case the daily backup task failed for any reason.

The back up folder is found in [I]sdcard/clockworkmod/backup/[/I] and automatically named [I]scheduledbackup-2011-06-02-05.00.00/[/I]

The '2011-06-02' is initially a problem as this is almost the opposite of Tasker's inbuilt [B]%DATE[/B] variable formatted as '6-2-11'. We need to use Tasker's [B]%DATE[/B] minus two days to match it to the dated backup file we want to delete.

Following the task through, you'll see that we transfer [B]%DATE[/B] to the created variable [B][B]%NDATE[/B][/B] before 'variable splitting' it by the '-' to leave 6 2 and 11 in [B]%NDATE1[/B], [B]%NDATE2[/B] and [B]%NDATE3[/B] respectively.

So, it's the 2nd of June for the sake of this example and using basic maths would mean that two days before this would be the 2-2 of June = 0th of June!? That's obviously no good to us... It should be the 31st May, so how do we easily do that...?!!? :eek: 

The answer is to use a 'pseudo-array' from [URL="http://groups.google.com/group/tasker/browse_thread/thread/1e1c531b900312e9#"]this thread[/URL] with credit to the brains of [URL="http://androidforums.com/members/unclemike.html"]UncleMike [/URL]. Now don't take a look at the below and give up reading, because it's actually a very simple and useful process. Honest(!): 

If we are in the 6th month of the year which is June and our -2 days are taking us back to the number of days in May, then we need to quickly reference the 6th month to the 31 days of May. Have a look below and you'll see that between the brackets of (6) is the number 31.
