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

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
