Regular expression question -

I need a regular expression to validate Social Security numbers.

The match number will be 9 digits (no spaces or dashes) and can not begin with three zero's (000) and also cannot begin with a nine (9).


002334444 Pass
888223333 Pass

000112222 Fail
911223333 Fail

grep -w '.\{9\}'

will kick out the ones that are 9 characters long

egrep -w '(9|000).*'

will kick out the failed ones
from the 9 or 000 at the start

grep '-'

will kick out -'s

grep '.[[:space:]].'

will kick out ones with spaces
