Compare two files using awk or sed, add values in a column if their previous fields are same

Hi All,

I have two files

file1:

abc,def,ghi,5,jkl,mno
pqr,stu,ghi,10,vwx,xyz
cba,ust,ihg,4,cdu,oqw

file2:

ravi,def,kishore
ramu,ust,krishna
joseph,stu,mike

I need two output files as follows

In my above example, each row in file1 has 6 fields and each row in file2 has 3 fields. I should compare field2 in both the files. If field2 is same in both the files then i should get the third field in file2 as the last field in file1.

output:

abc,def,ghi,5,jkl,mno,kishore
pqr,stu,ghi,10,vwx,xyz,mike
cba,ust,ihg,4,cdu,oqw,krishna


Also, If field3 in file1 is same as field3 in the next line then the field4 should add upto field4 in the next line and i should get a unique output as follows

ouput:

abc,def,ghi,15,jkl,mno
cba,ust,ihg,4,cdu,oqw


can somebody please help me with this as i require it pretty urgently. I am using sun solaris. If we can get the output using sed or awk that would be great. Any other way is also appreciated.

Thanks in advance..........

h5diff(1)						      General Commands Manual							 h5diff(1)

NAME
h5diff - Compares two HDF5 files and reports the differences. SYNOPSIS
h5diff file1 file2 [OPTIONS] [object1 [object2 ] ] DESCRIPTION
h5diff is a command line tool that compares two HDF5 files, file1 and file2, and reports the differences between them. Optionally, h5diff will compare two objects within these files. If only one object, object1, is specified, h5diff will compare object1 in file1 with object1 in file2. In two objects, object1 and object2, are specified, h5diff will compare object1 in file1 with object2 in file2. These objects must be HDF5 datasets. object1 and object2 must be expressed as absolute paths from the respective file's root group. Additional information, with several sample cases, can be found in the document H5diff Examples. OPTIONS
file1 file2 The HDF5 files to be compared. -h Print all differences. -r Print only the names of objects that differ; do not print the differences. These objects may be HDF5 datasets, groups, or named datatypes. -n count Print difference up to count differences, then stop. count must be a positive integer. -d delta Print only differences that are greater than the limit delta. delta must be a positive number. The comparison criterion is whether the absolute value of the difference of two corresponding values is greater than delta (e.g., |a-b| > delta, where a is a value in file1 and b is a value in file2). -p relative Print only differences that are greater than a relative error. relative must be a positive number. The comparison criterion is whether the absolute value of the difference 1 and the ratio of two corresponding values is greater than relative (e.g., |1-(b/a)| > relative where a is a value in file1 and b is a value in file2). object1 object2 Specific object(s) within the files to be compared. EXAMPLES
The following h5diff call compares the object /a/b in file1 with the object /a/c in file2: h5diff file1 file2 /a/b /a/c This h5diff call compares the object /a/b in file1 with the same object in file2: h5diff file1 file2 /a/b And this h5diff call compares all objects in both files: h5diff file1 file2 SEE ALSO
