comparing two dates.

Hi I have yesterday date and todays date stored in two variables.

Today date is stored in variable -- testdate=`date +%m/%d/%Y`
I found the yesterday date and stored in variable -- ydate=$month'/'$day1'/'$year

Now i am trying to find out whether $testdate is less that $ydate.

I am finding this way in a IF condition

if [[ $toed -le $shud ]]
then
echo "yes correct time"
else
echo "not correct time"
fi
else

when i am executing this the condition is failing and going to else part.

PLease help me on this.

Thanks in advance.
Raju

NAME
yesterday - print file names from the dump SYNOPSIS
yesterday [ -c ] [ -date ] files ... DESCRIPTION
Yesterday prints the names of the files from the most recent dump. Since dumps are done early in the morning, yesterday's files are really in today's dump. For example, if today is March 17, 1992, yesterday /adm/users prints /n/dump/1992/0317/adm/users In fact, the implementation is to select the most recent dump in the current year, so the dump selected may not be from today. With option -c, yesterday copies the dump file to the current directory. The date option selects other day's dumps, with a format of 2, 4, 6, or 8 digits of the form dd, mmdd, yymmdd, or yyyymmdd. Yesterday does not guarantee that the string it prints represents an existing file. EXAMPLES
Back up to yesterday's MIPS binary of vc: cd /mips/bin yesterday -c vc Temporarily back up to March 1's MIPS C library to see if a program runs correctly when loaded with it: bind `{yesterday -0301 /mips/lib/libc.a} /mips/lib/libc.a rm v.out mk v.out FILES
/n/dump SOURCE
/rc/bin/yesterday SEE ALSO
