locate special characters and digits using grep
Hello,
i have a file called test

hello1
"how" are you4
good"bye"
good7bye

i am trying to print all lines from test that either end with a digit or contain a double quote character anywhere on the line.

i did
grep -n '[0-9]$' test and was able to print lines ending with digits.
i also did grep -n '"' text and was able to print lines with ".
i don't know how to combine the two grep statements.
thanks.

iswdigit

ISWDIGIT(3)						     Linux Programmer's Manual						       ISWDIGIT(3)

NAME

       iswdigit - test for decimal digit wide character

SYNOPSIS

       #include <wctype.h>

       int iswdigit(wint_t wc);

DESCRIPTION

       The  iswdigit() function is the wide-character equivalent of the isdigit(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "digit".

       The wide-character class "digit" is a subclass of the wide-character class "xdigit", and therefore also a subclass  of  the  wide-character
       class "alnum", of the wide-character class "graph" and of the wide-character class "print".

       Being a subclass of the wide character class "print", the wide-character class "digit" is disjoint from the wide-character class "cntrl".

       Being  a  subclass  of the wide-character class "graph", the wide-character class "digit" is disjoint from the wide-character class "space"
       and its subclass "blank".

       Being a subclass of the wide-character class "alnum", the wide-character class "digit" is disjoint from the wide-character class "punct".

       The wide-character class "digit" is disjoint from the wide-character class "alpha" and therefore also disjoint from its subclasses "lower",
       "upper".

       The wide-character class "digit" always contains exactly the digits '0' to '9'.

RETURN VALUE

       The  iswdigit()	function  returns  nonzero  if wc is a wide character belonging to the wide-character class "digit".  Otherwise it returns
       zero.

CONFORMING TO

       C99.

NOTES

       The behavior of iswdigit() depends on the LC_CTYPE category of the current locale.
