Repeat output of last command w/o repeating last command
Is there a way to repeat the output of the last command for filtering without running the command again? All I could think of was to copy all the data to a text file and process it that way, is there another way? Like say I want to grep server.server.lan from a dtrace that was pages long after I already ran it, is there a way to filter output after its already been sent to terminal?

textutil::repeat(n) Text and string utilities, macro processing textutil::repeat(n)
__________________________________________________________________________________________________________________________________________________
NAME
textutil::repeat - Procedures to repeat strings.
SYNOPSIS
package require Tcl 8.2
package require textutil::repeat ?0.7?
::textutil::repeat::strRepeat text num
::textutil::repeat::blank num
_________________________________________________________________
DESCRIPTION
The package textutil::repeat provides commands to generate long strings by repeating a shorter string many times.
The complete set of procedures is described below.
::textutil::repeat::strRepeat text num
This command returns a string containing the text repeated num times. The repetitions are joined without characters between them. A
value of num <= 0 causes the command to return an empty string.
Note: If the Tcl core the package is loaded in provides the command string repeat then this command will be implemented in its
terms, for maximum possible speed. Otherwise a fast implementation in Tcl will be used.
::textutil::repeat::blank num
A convenience command. Returns a string of num spaces.
