Top Forums Shell Programming and Scripting Increment date in 'for' loop? Post 302142767 by aigles on Monday 29th of October 2007 01:27:23 PM

Numbers statrting with 0 are evaluated as octal numbers : 070820 is an invalid octal number.

A solution is to force decimal base evaluation :
Code:
#!/bin/sh

startdate=10#`/bin/date --date="10 weeks ago" +%y%m%d`
currentdate=10#`/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

This script will not give you any error, but i am not sure that the result is what you are expected.
Incrementng the date will give you invalid dates, for example :
070831+1=070832 <= Invalid date
