I have another similar matching problem. I want to compare the previous outputted result file (I will call it file3) with file4 (below) by 'offer','category','brand', 'company'. Like before, I want to extract exact matching rows' remaining columns ('quantity', 'offervalue') from file4 and add them to file3 columns, and remove no match rows from file3.

lam
LAM(1) BSD General Commands Manual LAM(1)NAME
lam -- laminate files
SYNOPSIS
lam [-f min.max] [-s sepstring] [-t c] file ...
lam [-p min.max] [-s sepstring] [-t c] file ...
DESCRIPTION
The lam utility copies the named files side by side onto the standard output. The n-th input lines from the input files are considered frag-
ments of the single long n-th output line into which they are assembled. The name `-' means the standard input, and may be repeated.
Normally, each option affects only the file after it. If the option letter is capitalized it affects all subsequent files until it appears
again uncapitalized. The options are described below:
-f min.max
Print line fragments according to the format string min.max, where min is the minimum field width and max the maximum field width.
If min begins with a zero, zeros will be added to make up the field width, and if it begins with a `-', the fragment will be left-
adjusted within the field.
-p min.max
Like -f, but pad this file's field when end-of-file is reached and other files are still active.
-s sepstring
Print sepstring before printing line fragments from the next file. This option may appear after the last file.
-t c The input line terminator is c instead of a newline. The newline normally appended to each output line is omitted.
To print files simultaneously for easy viewing use pr(1).
EXAMPLES
The command
lam file1 file2 file3 file4
joins 4 files together along each line. To merge the lines from four different files use
lam file1 -S "
" file2 file3 file4
Every 2 lines of a file may be joined on one line with
lam - - < file
and a form letter with substitutions keyed by `@' can be done with
lam -t @ letter changes
SEE ALSO join(1), paste(1), pr(1), printf(3)STANDARDS
Some of the functionality of lam is standardized as the paste(1) utility by IEEE Std 1003.2 (``POSIX.2'').
BUGS
The lam utility does not recognize multibyte characters.
