Full Discussion: Parsing file and extracting the useful data block
Top Forums Shell Programming and Scripting Parsing file and extracting the useful data block Post 65559 by arminder on Monday 7th of March 2005 08:37:53 AM

Sorry Guys, maybe I didn't put it correctly. The amount of "useful data" isn't known i.e. it may be 2 lines long or 10/20/100 i.e. no same occurences. Same goes for the "sample data" too. Its only that "start" and "end" is that can tell me where to start from and where to end.

Later I figured a way to print the block and so currently I am using following in awk file:

/^start/./^end/

Thereafter I grep out (grep -v) the start and end text.

Cheers

Arminder

PTARGREP(1)						 Perl Programmers Reference Guide					       PTARGREP(1)

NAME

       ptargrep - Apply pattern matching to the contents of files in a tar archive

SYNOPSIS

	 ptargrep [options] <pattern> <tar file> ...

	 Options:

	  --basename|-b     ignore directory paths from archive
	  --ignore-case|-i  do case-insensitive pattern matching
	  --list-only|-l    list matching filenames rather than extracting matches
	  --verbose|-v	    write debugging message to STDERR
	  --help|-?	    detailed help message

DESCRIPTION

       This utility allows you to apply pattern matching to the contents of files contained in a tar archive.  You might use this to identify all
       files in an archive which contain lines matching the specified pattern and either print out the pathnames or extract the files.

       The pattern will be used as a Perl regular expression (as opposed to a simple grep regex).

       Multiple tar archive filenames can be specified - they will each be processed in turn.

OPTIONS

       --basename (alias -b)
	   When matching files are extracted, ignore the directory path from the archive and write to the current directory using the basename of
	   the file from the archive.  Beware: if two matching files in the archive have the same basename, the second file extracted will
	   overwrite the first.

       --ignore-case (alias -i)
	   Make pattern matching case-insensitive.

       --list-only (alias -l)
	   Print the pathname of each matching file from the archive to STDOUT.  Without this option, the default behaviour is to extract each
	   matching file.

       --verbose (alias -v)
	   Log debugging info to STDERR.

       --help (alias -?)
	   Display this documentation.
