Compare files with fields separated with semicolon
Dear experts

I have files like
Code:
ABD : 5869 events, relative ratio : 1.173800E-01 , sum of ratios : 1.173800E-01 
VBD : 12147 events, relative ratio : 2.429400E-01 , sum of ratios : 3.603200E-01 
SDF : 17000 events, relative ratio : 3.400000E-01 , sum of ratios : 7.003200E-01 
OIP: 14984 events, relative ratio : 2.996800E-01 , sum of ratios : 1.000000E+00

so, the values I want to compare are separated with a ':' followed by a space -- I want to use file1 as reference, and compare file2 value by value and line by line but comparing only columns 2,3 etc until the end of each line, and if I have a mismatch by a certain ratio (valueA/valueB) while comparing each given column on each given line do something, (actionA) otherwise do actionB

Thanks in advance

sum

sum(1B) 					     SunOS/BSD Compatibility Package Commands						   sum(1B)

NAME

       sum - calculate a checksum for a file

SYNOPSIS

       /usr/ucb/sum file...

DESCRIPTION

       sum  calculates	and  displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
       look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an  algorithm	which  may
       yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
       been transferred between machines with different-sized ints.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       sum(1), wc(1), attributes(5), largefile(5)

DIAGNOSTICS

       Read error is indistinguishable from EOF on most devices; check the block count.

NOTES

       sum and /usr/bin/sum (see sum(1)) return different checksums.

       This utility is obsolete.
