Hi Everyone,
I have:
$val="QQ3_1899_CD4".
The output will be:
1899.
I did $val =~ /(\d+)/g; the output is 318994, then i use substr to get those 1899. This is not efficient.
Is any simple way, like just one line can do? Thanks (1 Reply)

iswpunct
ISWPUNCT(3) Linux Programmer's Manual ISWPUNCT(3)NAME
iswpunct - test for punctuation or symbolic wide character
SYNOPSIS
#include <wctype.h>
int iswpunct(wint_t wc);
DESCRIPTION
The iswpunct() function is the wide-character equivalent of the ispunct(3) function. It tests whether wc is a wide character belonging to
the wide-character class "punct".
The wide-character class "punct" is a subclass of the wide-character class "graph", and therefore also a subclass of the wide-character
class "print".
The wide-character class "punct" is disjoint from the wide-character class "alnum" and therefore also disjoint from its subclasses "alpha",
"upper", "lower", "digit", "xdigit".
Being a subclass of the wide-character class "print", the wide-character class "punct" is disjoint from the wide-character class "cntrl".
Being a subclass of the wide-character class "graph", the wide-character class "punct" is disjoint from the wide-character class "space"
and its subclass "blank".
RETURN VALUE
The iswpunct() function returns nonzero if wc is a wide-character belonging to the wide-character class "punct". Otherwise, it returns
zero.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

|iswpunct() | Thread safety | MT-Safe locale |

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99.
NOTES
The behavior of iswpunct() depends on the LC_CTYPE category of the current locale.
This function's name is a misnomer when dealing with Unicode characters, because the wide-character class "punct" contains both punctuation
characters and symbol (math, currency, etc.) characters.
