if [ $NOWDATE -gt $STARTDATE ] , date comparison correct syntax?

i've looked at a bunch of the date comparison threads on these boards but unfortunately not been able to figure this thing out yet. still confused by some of the way conditionals handle variables...

here is what i where i am now...

Code:
# a bunch of initializition steps are here ...
STARTDATE=`date +%Y%m%d`
 
while [ 1 ] # loop running all the time. 
do

NOWDATE=`date +%Y%m%d`

# if day changes then i want to reinitialize
if [ $NOWDATE -gt $STARTDATE ] 
then
# do all that initiallization again 
fi

# ... a bunch of other code in here

done

but that if statement doesn't work. any tips?

thanks,
dan

fstrcmpi(3)						     Library Functions Manual						       fstrcmpi(3)

NAME
fstrcmpi - fuzzy comparison of two strings SYNOPSIS
#include <fstrcmp.h> #define FSTRCMPI_IDENTICAL #define FSTRCMPI_THRESHOLD #define FSTRCMPI_ERROR int fstrcmpi(const char *string1, const char *string2); DESCRIPTION
The fstrcmpi() function compares the two strings, string1 and string2. RETURN VALUE
The fstrcmpi function returns an int value between 0 and FSTRCMPI_IDENTICAL. A value of 0 means the strings are utterly un-alike. A value of FSTRCMPI_IDENTICAL means the strings are identical. A value of more than FSTRCMPI_THRESHOLD (it lies between 0 and FSTRCMPI_IDENTICAL) would be considered "similar" by most people. A value of FSTRCMPI_ERROR (always negative) indicates a malloc(3) failure. SEE ALSO
