Summary: pcregrep doesn't match empty/blank lines
Product: PCRE
Version: 8.32
Platform: x86
OS/Version: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Code
AssignedTo: ph10@???
ReportedBy: goathunter@???
CC: pcre-dev@???
I searched, but didn't see a similar report.
In an older version (sorry, I'm not exactly sure what version this worked in),
I could use pcregrep to find blank lines in a file using the pattern "^$". That
doesn't work in the current version (8.32) of pcregrep. I've experienced this
under both Linux and my port to OpenVMS.
I created a file x.x that consisted of a blank line, followed by a line
containing the word "hello".
On Linux (CentOS 6.4 32-bit):
------------------
[goathunter@localhost pcre-8.32]$ grep "^$" x.x
[goathunter@localhost pcre-8.32]$ ./pcregrep "^$" x.x
[goathunter@localhost pcre-8.32]$
------------------
I've tried to debug this myself, but haven't come up with any reason yet.
If I use my old pcregrep.c with this line:
#define VERSION "4.4 29-Nov-2006"
that pattern matches blank lines as expected. I saw this problem at least as
far back as 8.02.
Thanks for any help or insight.
