Full Discussion: How to print the "grep" result as specified keyword order?
Top Forums UNIX for Beginners Questions & Answers How to print the "grep" result as specified keyword order? Post 303037632 by RudiC on Thursday 8th of August 2019 08:47:53 AM

For reading the keywords from file, try grep -f id.txt


For keeping the sequence as given in id.txt, you could write e.g. an awk or perl script. Or try this very inefficient shell (untested):
Code:
while read ID
  do   grep $ID content.xls
  done < id.txt

Don't try with large files, as it scans through the entire content.xls for every single keyword in id.txt
Reading the content.xls file into an associated array indexed by the key value and then printing it according to the keys found in id.txt is left as an exercise for the reader.

text::worddiff::html

Text::WordDiff::HTML(3pm)				User Contributed Perl Documentation				 Text::WordDiff::HTML(3pm)

Name
       Text::WordDiff::HTML - XHTML formatting for Text::WordDiff

Synopsis
	   use Text::WordDiff;

	   my $diff = word_diff 'file1.txt', 'file2.txt'; { STYLE => 'HTML' };
	   my $diff = word_diff $string1,   $string2,    { STYLE => 'HTML' };
	   my $diff = word_diff *FH1,	     *FH2,	   { STYLE => 'HTML' };
	   my $diff = word_diff &reader1,   &reader2,    { STYLE => 'HTML' };
	   my $diff = word_diff @records1,  @records2,   { STYLE => 'HTML' };

	   # May also mix input types:
	   my $diff = word_diff @records1,  'file_B.txt', { STYLE => 'HTML' };

Description
       This class subclasses Text::WordDiff::Base to provide a XHTML formatting for Text::WordDiff. See Term::WordDiff for usage details. This
       class should never be used directly.

       Text::WordDiff::HTML formats word diffs for viewing in a Web browser. The diff content is highlighted as follows:

       o   "<div class="file">"

	   This element contains the entire contents of the diff "file" returned by "word_diff()". All of the following elements are subsumed by
	   this one.

	   o   "<span class="fileheader">"

	       The header section for the files being "diff"ed, usually something like:

		 --- in.txt    Thu Sep	1 12:51:03 2005
		 +++ out.txt   Thu Sep	1 12:52:12 2005

	       This element immediately follows the opening "file" "<div>" element, but will not be present if Text::WordDif cannot deterimine the
	       file names for both files being compared.

	   o   "<span class="hunk">"

	       This element contains a single diff "hunk". Each hunk may contain the following elements:

	       o   "<ins>"

		   Inserted content.

	       o   "<del>"

		   Deleted content.

       You may do whatever you like with these elements and classes; I highly recommend that you style them using CSS. You'll find an example CSS
       file in the eg directory in the Text-WordDiff distribution.
