Full Discussion: Simple regexp doesn't work
Top Forums Shell Programming and Scripting Simple regexp doesn't work Post 302428039 by dkarr on Tuesday 8th of June 2010 03:32:21 PM

I'm on Solaris 10, if that matters, but my egrep appears to be different from what you have.

Character classes are recognized as "[:blank:]", not "[[:blank:]]" (according to the regex(5) man page). In any case, it has no trouble recognizing "\s". I get the same results with "\s*" as I get with "[:blank:]*". I get no results with "[[:blank:]]".

To recap, I get lines with '^\*\*\*\*\s*[a-z]*\s*' and '^\*\*\*\*[:blank:]*[a-z]*[:blank:]*', but not '^\*\*\*\*[:blank:]+[a-z]+[:blank:]+', '^\*\*\*\*[:blank:]+[a-z]+[:blank:]+Fri', '^\*\*\*\*[:blank:]*[a-z]*[:blank:]*Fri', or '^\*\*\*\*\s*[a-z]*\s*Fri'.

There appear to be two issues here. One I can work around, and the other I cannot. For some reason, using "+" instead of "*" never matches. In my case, I can use "*" if I can't get "+" to work. The other issue is that adding "Fri" to the end of a working expression makes it find no lines.

iswblank

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

NAME

       iswblank - test for whitespace wide character

SYNOPSIS

       #include <wctype.h>

       int iswblank(wint_t wc);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       iswblank():
	      _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

DESCRIPTION

       The  iswblank() function is the wide-character equivalent of the isblank(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "blank".

       The wide-character class "blank" is a subclass of the wide-character class "space".

       Being a subclass of the wide-character class "space", the wide-character class "blank" is disjoint from the  wide-character  class  "graph"
       and therefore also disjoint from its subclasses "alnum", "alpha", "upper", "lower", "digit", "xdigit", "punct".

       The wide-character class "blank" always contains at least the space character and the control character '	'.

RETURN VALUE

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

ATTRIBUTES

       For an explanation of the terms used in this section, see attributes(7).

       +-----------+---------------+----------------+
CONFORMING TO

       POSIX.1-2001, POSIX.1-2008.

NOTES

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