OK. So your sample input contains duplicates. (And you refuse to tell us why.) Getting rid of duplicates is easy.

You tell us that dates are to be in ascending order and suffixes are to be in descending order, but your expected output above has dates in a seemingly random order (assuming that the timestamp is part of what you are calling the date) and suffixes in increasing order (not decreasing). If the timestamp is to be ignored when sorting the data, then the suffices you say you want are in random order in your list above.

And, you say: "I regret if I could not present it properly, as there are couple of file types which appears until third character of every files ( ie fn, ski etc )." Is this supposed to mean something in the way the output is to be sorted??? You have not shown us any input or output that has more than a single sequence of two or three letters that appear in every file in each list you have shown us.

I am sorry, but I am unable to ascertain any pattern in the output you want. And, even if we assume that the line marked in red above is a typo, the output you have shown us doesn't come close to what you said you want.

I give up.

grokevt-addlog

grokevt-addlog(1)														 grokevt-addlog(1)

NAME

       grokevt-addlog - A tool for adding a raw event log to an existing GrokEVT database.

SYNOPSIS

       grokevt-addlog  database-dir  evt-file new-type base-type .SH DESCRIPTION grokevt-addlog takes a raw event log (.evt file) and adds it to a
       pre-built database generated by grokevt-builddb(1). This new log file will be set up to use the message templates of another log, as deter-
       mined by the user.

       This  tool  is  primarily  useful for processing deleted logs and log fragments found on a system. While it is possible to use the database
       generated from one system with the logs of another, this is not recommended for investigations unless no alternatives exist.

ARGUMENTS

       grokevt-addlog uses the following arguments:

       database-dir
	      The base directory for the database generated previously by grokevt-builddb(1).

       evt-file
	      The file to be added to the database.

       new-type
	      The new log type/name that evt-file will take on.  This is the name that will need to be	used  later  with  grokevt-parselog(1)	to
	      access the new log. This type must not already exist in the database.

       base-type
	      The  existing  log  type that this new log will be based on. The message templates from this type will be used with the new log when
	      parsing. This type must exist in the current database.

BUGS

       Probably several. This particular script has not been extensively tested.
