Hello smenago,

You was not clear about requirement, based on my assumptions which are (You have 2 files named b_file and c_file as follows.)
Code:
cat b_file
11977 DAR.V3.20150209.1.CSV
3295 DAR.V3.20150209.1.CSV
1721 DAR.V2.20150210.1.CSV
 
cat c_file
tom 11977
charlie 3295
steve 1721

Then as per your expected output I can suggest following.
Code:
awk 'FNR==NR{A[$1]=$2;next} ($2 in A){print $1 OFS A[$2]}' b_file c_file

Output will be as follows.
Code:
tom DAR.V3.20150209.1.CSV
charlie DAR.V3.20150209.1.CSV
steve DAR.V2.20150210.1.CSV

If you are happy with above awk command then you can redirect it's output to a file named > /tmp/dar3.out.

Hope this helps, if my assumptions are not correct, please do let us know the expected output with os details.


NOTE: On Solaris/SunOS systems, you need to change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk


EDIT: Sorry Corona, seems we have posted on same time, please do remove this post if needed until OP comes back with answer.


Thanks,
R. Singh

Image::ExifTool::Import(3pm)				User Contributed Perl Documentation			      Image::ExifTool::Import(3pm)

NAME

       Image::ExifTool::Import - Import CSV and JSON database files

SYNOPSIS

	   use Image::ExifTool::Import qw(ReadCSV ReadJSON);

	   $err = ReadCSV($csvFile, \%database);

	   $err = ReadJSON($jsonfile, \%database);

DESCRIPTION

       This module contains routines for importing tag information from CSV (Comma Separated Value) and JSON (JavaScript Object Notation) database
       files.

EXPORTS

       Exports nothing by default, but ReadCSV and ReadJSON may be exported.

METHODS

   ReadCSV / ReadJSON
       Read CSV or JSON file into a database hash.

       Inputs:
	   0) CSV file name.

	   1) Hash reference for database object.

	   2) Optional flag to set '-' values to undef in the database.  (Used for deleting tags.)

	   3) [ReadJSON only] Optional character set for converting Unicode escape sequences in strings.  Defaults to "UTF8".  See the ExifTool
	   Charset option for a list of valid settings.

       Return Value:
	   These functions return an error string, or undef on success and populate the database hash with entries from the CSV or JSON file.
	   Entries are keyed based on the SourceFile column of the CSV or JSON information, and are stored as hash lookups of tag name/value for
	   each SourceFile.
