Full Discussion: Problem with getting awk to multiply a field by a value set based on condition of another field
Top Forums UNIX for Beginners Questions & Answers Problem with getting awk to multiply a field by a value set based on condition of another field Post 303043629 by Scrutinizer on Sunday 2nd of February 2020 02:23:36 PM

Hi some quick thought on the last code snippet:
In awk the middle section is processed per line, so you should leave out:
for(i=1;i<=NR;i++)
The results should be stored in arrays so they can be used in the END section.
The END section contains code after all lines have been read in the middle section,
so the following has no business there:
Code:
      a[$1]=$2;
      b[$4]=$4*$w

text::context

Text::Context(3pm)					User Contributed Perl Documentation					Text::Context(3pm)

NAME

       Text::Context - Handle highlighting search result context snippets

SYNOPSIS

	 use Text::Context;

	 my $snippet = Text::Context->new($text, @keywords);

	 $snippet->keywords("foo", "bar"); # In case you change your mind

	 print $snippet->as_html;
	 print $snippet->as_text;

DESCRIPTION

       Given a piece of text and some search terms, produces an object which locates the search terms in the message, extracts a reasonable-length
       string containing all the search terms, and optionally dumps the string out as HTML text with the search terms highlighted in bold.

   new
       Creates a new snippet object for holding and formatting context for search terms.

   keywords
       Accessor method to get/set keywords. As the context search is done case-insensitively, the keywords will be lower-cased.

   paras
	   @paras = $self->paras($maxlen)

       Return shortened paragraphs to fit together into a snippet of at most $maxlen characters.

   as_text
       Calculates a "representative" string which contains the given search terms. If there's lots and lots of context between the terms, it's
       replaced with an ellipsis.

   as_html([ start => "<some tag>", end => "<some end tag>" ])
       Markup the snippet as a HTML string using the specified delimiters or with a default set of delimiters ("<span class="quoted">").
