Question Increment date in 'for' loop?

Hi Guys,

My first post..Smilie

Right...I want to move existing files (with some date in their name) currently in $mainftp, to $mainfolder/$foldate/system1.

I'd like to be able to increment date in the for loop? Is this possible or should I use a different technique.

The script return the following error

./movediselogs.sh: line 8: ((: foldate=070820: value too great for base (error token is "070820")

Hope that makes sense...

-----------------------

#!/bin/sh

startdate=`/bin/date --date="10 weeks ago" +%y%m%d`
currentdate=`/bin/date +%y%m%d`
mainfolder=/data/backup
mainftp=/ftp/upload/ftpsystem1

for ((foldate=$startdate; $foldate < $currentdate; foldate++))
do
mkdir $mainfolder/$foldate/system1
mv $mainftp/*$foldate* $mainfolder/$foldate/system1
done

-----------------------

Many Thanks
SunnyK
