Comparing 2 files

I'm hoping you can help me with this problem (I posted this yesterday but the posting and replies were lost). We just moved from AIX to Solaris. I have a script which is doing a diff on 2 files to get a file of just differences to be applied. The Solaris diff is creating a different 'diff' file than the AIX


For example I took the files and did the same command on both AIX and Solaris machines.
In looking at a portion of the file, this is what is different:


Old file: (FILE1)


NBBAKER BROOK E7A0A1
NBBAKER BROOK E7A0A2
NBBAKER BROOK E7A0A3
NBSAINT-FRANCOIS-DE-MADAWASKA E7A1A1

QCSHEFFORD J2M1A5
QCSHEFFORD J2M1A6
QCSHEFFORD J2M1A7
QCSHEFFORD J2M1A8
QCSHEFFORD J2M1A9



So the differences should be to add the records: E7A0A4
J2M0A5
J2M0A6 to file1



Diff statement on AIX:


85035a85072
> NBLAC BAKER E7A0A4
233803a233943,233944
> QCSHEFFORD J2M0A5
> QCSHEFFORD J2M0A6


Diff statement on Solaris:

85035a85072
> NBLAC BAKER E7A0A4
233804,233805c233943,233946
< QCSHEFFORD J2M1A1
< QCSHEFFORD J2M1A2
---
> QCSHEFFORD J2M0A5
> QCSHEFFORD J2M0A6
> QCSHEFFORD J2M1A1
> QCSHEFFORD J2M1A2


I tried using the bdiff, diff -h commands to see if that made any difference
but it doesn't. Any idea what is causing the file to be created differently?
I just want to see the same layout as the AIX file. I don't understand why
it shows the records to be added on Solaris as sometimes just the record as in E7A0A4 and sometimes showing what records were in both files as in J2M1A1.

Thanks,

Helen

hdixon,

Both the diff's are correct -- if you apply the editing commands (ed) in the diff to the 2nd file it will produce the first file.
