Hello!
My final exam in my Linux class is tomorrow, and I was just reviewing the grep and sed commands. I came across an example, by which I got stumped: it asks to provide a sed command that deletes all lines that contain exactly 3 to 5 digit strings, from a file.
In this case, I created a... (3 Replies)

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.
