Assume both the files are sorted on first field.

Code:
f1
a1,a2,a3,a4,a5,a6
b1,b21,b31,b4,b5,b5
c1,c2,c3,c4,c5,c6
 
f2
a1,a2,a3,a4,a5,a6
b1,b2,b3,b4,b5,b6
c1,c2,c3,c4,c51,c61
d1,d2,d3,d4,d5,d6
 
The Output f3
b1,b21,b31,b4,b5,b6
c1,c2,c3,c4,c5,c6

I don't want to compare line by line , this may be required to tuke the data in some field.
I am just looking for Perl or unix script, how should I proceed about this.

Thanks
Dgmm
Welcome to the forum.

I could not get the grep to work, either.

On the other hand, I don't see where this line in f3 comes from:
Code:
b1,b21,b31,b4,b5,b6

Is that a typo? ... cheers, drl

dist::zilla::plugin::filefinder::byname

Dist::Zilla::Plugin::FileFinder::ByName(3pm)		User Contributed Perl Documentation	      Dist::Zilla::Plugin::FileFinder::ByName(3pm)

NAME

       Dist::Zilla::Plugin::FileFinder::ByName - FileFinder matching on pathnames

VERSION

       version 4.300020

SYNOPSIS

       In your dist.ini:

	 [FileFinder::ByName / MyFiles]
	 dir   = bin	 ; look in the bin/ directory
	 dir   = lib	 ; and the lib/ directory
	 file  = *.pl	 ; for .pl files
	 match = .pm$	 ; and for .pm files
	 skip  = ignore  ; that don't have "ignore" in the path

DESCRIPTION

       FileFinder::ByName is a FileFinder that selects files by matching the criteria you specify against the pathname.

       There are three types of criteria you can use.  "dir" limits the search to a particular directory.  "match" is a regular expression that
       must match the pathname.  "skip" is a regular expression that must not match the pathname.

       Each key can be specified multiple times.  Multiple occurrences of the same key are ORed together.  Different keys are ANDed together.
       That means that to be selected, a file must be located in one of the "dir"s, must match one of the "match" regexs, and must not match any
       of the "skip" regexs.

       Note that "file" and "match" are considered to be the same key.	They're just different ways to write a regex that the pathname must match.

       Omitting a particular key means that criterion will not apply to the search.  Omitting all keys will select every file in your dist.

       Note: If you need to OR different types of criteria, then use more than one instance of FileFinder::ByName.  A FileFinderUser should allow
       you to specify more than one FileFinder to use.

ATTRIBUTES

   dir
       The file must be located in one of the specified directories (relative to the root directory of the dist).

   file
       The filename must match one of the specified patterns (which are converted to regexs using Text::Glob and combined with any "match" rules).

   match
       The pathname must match one of these regular expressions.

   skip
       The pathname must not match any of these regular expressions.
