Yes, you got the requirements right.

I was uniquly sorting on basis of key columns, like if we have 3rd and 5th as key column, I will use sort command like
Code:
sort -k3,3 -k5,5 | uniq

Code:
What will the maximum count be between lines with identical key pairs?

I am not sure what above means.

Before comparing files with each other, we should see in same files, if 3 and 5 are key columns, and one file has same records many times like

Code:
[1]|[2]|[3]|[4]|[5]
 A    B    1   C    2
 A    B    1   C    2
 A    B    1   C    2
 D    E    3   F    4

then
Code:
 A    B    1   C    2

should be considered as single record.

and if

Code:
[1]|[2]|[3]|[4]|[5]
 A    B    1   C    2
 A    B    1   D    2
 A    E    1   F    2
 D    E    3   F    4

then records

Code:
 A    B    1   C    2
 A    B    1   D    2
 A    E    1   F    2

should treated as error records and moved to .err file.

Let me know if that what you want to ask.

Regards,
Manu

rmdel

rmdel(1)						      General Commands Manual							  rmdel(1)

Name
       rmdel - remove a delta from an SCCS file

Syntax
       rmdel -r files

Description
       The command removes the delta specified by the SID from each named SCCS file.  The delta to be removed must be the most recent delta in its
       branch in the delta chain of each named SCCS file.  In addition, the  specified delta must not be that of a version being  edited  for  the
       purpose	of  making  a delta, for example, if a p-file exists for the named SCCS file, the  specified delta must not appear in any entry of
       the p-file).  For further information, see

       If a directory is named, behaves as though each file in the directory were specified as a named file, except that non-SCCS files (last com-
       ponent  of the path name does not begin with s.)  and unreadable files are silently ignored.  If - is given as the name, the standard input
       is read and each line of the standard input is taken to be the name of an SCCS file to be processed.  Non-SCCS files and  unreadable  files
       are silently ignored.

       Certain permissions are necessary to remove a delta.  If you make a delta or own the file and directory, you can remove it.

Options
       -rSID   Specifies the delta version number.

Diagnostics
       Use for explanations.
