Problem with Date validation

Hi All,

I've to validate a date input for the format YYYYMMDD. The input should be of 8 digits with only numeric values.

I tried the following

Code:
echo $1 | grep '^[0-9]\{8}$/p'
if [ $? -eq 0 ]
then
 echo "Valid"
else
 echo "invalid"

I get the error,

Code:
grep: RE error 16: Bad number.

Any help will be appreciated.
Thanks,
Sumesh
