I have searched the internet (including these forums) and perhaps I'm not using the right wording.
What I'm looking for is a function (preferably C) that analyzes the similitude of two numerical or near-numerical values, and returns either a true/false (match/nomatch) or a return code that... (4 Replies)

Dear All,
assume i have a file with content:

In the file1 below if $9 and $12 are . (dot) then the value in $8 of file1 is used as a key (exact match) to lookup in each $2 of file2, when a match is found then the value of $4

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
FILES
/tmp/d3?????
/usr/lib/diff3
SEE ALSO diff(1)BUGS
Text lines that consist of a single `.' will defeat -e.
Files longer than 64K bytes won't work.
