Match the columns between two files and output
Hi Help,

I have two files namely a.txt and b.txt

a.txt looks like

Code:
a.txt
1 2 2
1 3 3
2 4 4
4 5 6
6 7 7

b.txt looks like,
Code:
b.txt
1 2 1
1 3 2
2 4 3
3 4 4
4 5 5
6 7 6

a.txt and b.txt are quite similar in the form that
Code:
$1 and $2 of both the files matches

. Also,b.txt has one extra line, line 4.
I would like to first remove that line completely and then the output should look like
Code:
$1 of a.txt,$2 of a.txt,$3 of a.txt,$4 of b.txt

.

Below is the output file.


Code:
op.txt
1 2 2 1
1 3 3 2
2 4 4 3
4 5 6 5
6 7 7 6

Please help.
Thanks.

gensprep

gensprep(8)							 ICU 50.1.2 Manual						       gensprep(8)

NAME

       gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS

       gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]

DESCRIPTION

       gensprep reads filtered RFC 3454 files and compiles their information into a binary form.  The resulting file, <name>.icu, can then be read
       directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.

       The files read by gensprep are described in the FILES section.

OPTIONS

       -h, -?, --help
	      Print help about usage and exit.

       -v, --verbose
	      Display extra informative messages during execution.

       -c, --copyright
	      Include a copyright notice into the binary data.

       -s, --sourcedir source
	      Set the source directory to source.  The default source directory is specified by the environment variable ICU_DATA.

       -d, --destdir destination
	      Set the destination directory to destination.  The default destination directory is specified by the environment variable ICU_DATA.

ENVIRONMENT

       ICU_DATA  Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/.  Some tools in ICU depend on the presence of the
		 trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.

FILES

       The  following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
       izationCorrections.txt.

       rfc3453_A_1.txt	   Contains the list of unassigned codepoints in Unicode version 3.2.0....

       rfc3454_B_1.txt	   Contains the list of code points that are commonly mapped to nothing....

       rfc3454_B_2.txt	   Contains the list of mappings for casefolding of  code points when Normalization form NFKC is specified....

       rfc3454_C_X.txt	   Contains the list of code points that are prohibited for IDNA.

       NormalizationCorrections.txt
			   Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
