most current entries of particular pattern
I have many files coming from different objects in a text file.
All objects have a file of the each dates....i.e (11july,12 july, ... so on) as convention of (object1_july11,object2_july11,object3_july11,object1_july12,object3_july12.. so on).
Now sometimes the file from object stops coming in text file.
It needs me to get the most current date for each object in another text file so that we can track from which object the file is not coming.
Thanks in advance.

local(n) [incr Tcl] local(n)
__________________________________________________________________________________________________________________________________________________
NAME
local - create an object local to a procedure
SYNOPSIS
itcl::local className objName ?arg arg ...?
_________________________________________________________________
DESCRIPTION
The local command creates an [incr Tcl] object that is local to the current call frame. When the call frame goes away, the object is auto-
matically deleted. This command is useful for creating objects that are local to a procedure.
As a side effect, this command creates a variable named "itcl-local-xxx", where xxx is the name of the object that is created. This vari-
able detects when the call frame is destroyed and automatically deletes the associated object.
EXAMPLE
In the following example, a simple "counter" object is used within the procedure "test". The counter is created as a local object, so it
is automatically deleted each time the procedure exits. The puts statements included in the constructor/destructor show the object coming
and going as the procedure is called.
itcl::class counter {
private variable count 0
constructor {} {
puts "created: $this"
}
destructor {
puts "deleted: $this"
}
method bump {{by 1}} {
incr count $by
}
method get {} {
return $count
}
}
proc test {val} {
local counter x
for {set i 0} {$i < $val} {incr i} {
x bump
}
return [x get]
}
set result [test 5]
puts "test: $result"
set result [test 10]
puts "test: $result"
puts "objects: [itcl::find objects *]"
KEYWORDS
class, object, procedure
itcl local(n)
