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.

Spreadsheet::ParseExcel::Simple(3pm)			User Contributed Perl Documentation		      Spreadsheet::ParseExcel::Simple(3pm)

NAME

       Spreadsheet::ParseExcel::Simple - A simple interface to Excel data

SYNOPSIS

	 my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls');
	 foreach my $sheet ($xls->sheets) {
	    while ($sheet->has_data) {
		my @data = $sheet->next_row;
	    }
	 }

DESCRIPTION

       This provides an abstraction to the Spreadsheet::ParseExcel module for simple reading of values.

       You simply loop over the sheets, and fetch rows to arrays.

       For anything more complex, you probably want to use Spreadsheet::ParseExcel directly.

BOOK METHODS

       read

	 my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls');

       This opens the spreadsheet specified for you. Returns undef if we cannot read the book.

       sheets

	 @sheets = $xls->sheets;

       Each spreadsheet can contain one or more worksheets. This fetches them all back. You can then iterate over them, or jump straight to the
       one you wish to play with.

       book

	       my $book = $xls->book;

       The Spreadsheet::ParseExcel object we are working with. You can use this if you need to manipulate it in ways that this interface doesn't
       allow.

SHEET METHODS

       These methods can be called on each sheet returned from $xls->sheets:

       has_data

	 if ($sheet->has_data) { ... }

       This lets us know if there are more rows in this sheet that we haven't read yet. This allows us to differentiate between an empty row, and
       the end of the sheet.

       next_row

	 my @data = $sheet->next_row;

       Fetch the next row of data back.

       sheet

	       my $obj = $sheet->sheet;

       The underlying Spreadsheet::ParseExcel object for the worksheet. You can use this if you need to manipulate it in ways that this interface
       doesn't allow (e.g. asking it for the sheet's name).
