grep -E drives me crazy
Hi there,

I'm new here. I registered my self today with this board because I hope to get some help before I'll become a slavering maniac.
I'm really desperate, since I'm trying for hours(really!) to let grep search a pattern that goes about 2 lines.
The pattern is as follows:
Handle 0x000xxxxxxx
Memory Module Information

I tried it as follows:
grep -i -E 'handle .*memory module information' -A 8

I also did that:
grep -i -E 'handle .*memory module information/m' -A 8

and that:
grep -i -E '^handle .*[\n]memory module information' -A 8

For the last 3 and a half hours I read so many pages about egrep, but nothing answers my question. It simply doesn't work.

Help me please (with sugar on top)

Best regards
darkelf

bzegrep

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME

       bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression

SYNOPSIS

       bzgrep [ grep_options ] [ -e ] pattern filename...
       bzegrep [ egrep_options ] [ -e ] pattern filename...
       bzfgrep [ fgrep_options ] [ -e ] pattern filename...

DESCRIPTION

       Bzgrep  is  used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep.  If no file is specified,
       then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and  fed	to
       grep.

       If  bzgrep  is  invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, bzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	bzgrep string files
	   for csh: (setenv GREP fgrep; bzgrep string files)
