Top Forums Shell Programming and Scripting searching and editing file contents Post 302165064 by jayana on Wednesday 6th of February 2008 05:08:45 PM

Hi friends, thanks for all your responses, but I have a concern here that the end need not always be after 1 line of the ID. we may have more information after the ID, but END just marks the end of the block of information.
Once I get the line number for ID (say line 35) using the grep -n, is there a way to search for the first instance of END(line 40) after it? I can get start as 2 lines behind ID (line 33) .
Once I have line 33 & 40, can I cut the lines in between and get the 8 lines into a new file?
Awk seems a little complex to understand, hence trying to explore more on grep solutions. The copy paste of awk command at shell prompt:awk '/Start/{i=0}/id:'"${ID}"'/{f=1}{a[i]=$0;i++}/end/&&f{exit}END{for (j=1;j<i-1;++j)print a[j]}' file
gave me syntax error at line 1, i could not debug the same.

Thanks for all your support

lwp-dump

LWP-DUMP(1)						User Contributed Perl Documentation					       LWP-DUMP(1)

NAME

       lwp-dump - See what headers and content is returned for a URL

SYNOPSIS

       lwp-dump [ options ] URL

DESCRIPTION

       The lwp-dump program will get the resource indentified by the URL and then dump the response object to STDOUT.  This will display the
       headers returned and the initial part of the content, escaped so that it's safe to display even binary content.	The escapes syntax used is
       the same as for Perl's double quoted strings.  If there is no content the string "(no content)" is shown in its place.

       The following options are recognized:

       --agent str
	   Override the user agent string passed to the server.

       --keep-client-headers
	   LWP internally generate various "Client-*" headers that are stripped by lwp-dump in order to show the headers exactly as the server
	   provided them.  This option will suppress this.

       --max-length n
	   How much of the content to show.  The default is 512.  Set this to 0 for unlimited.

	   If the content is longer then the string is chopped at the limit and the string "...
(### more bytes not shown)" appended.

       --method str
	   Use the given method for the request instead of the default "GET".

       --parse-head
	   By default lwp-dump will not try to initialize headers by looking at the head section of HTML documents.  This option enables this.
	   This corresponds to "parse_head" in LWP::UserAgent.

       --request
	   Also dump the request sent.

SEE ALSO

       lwp-request, LWP, "dump" in HTTP::Message
