We are not here to do your homework for you. Leaving section 3 in the homework template blank isn't a good starting point.

If you put in some effort and show us what you have tried, we can help you hone your solution to one that will get the job done. If you aren't willing to show us that you are making an effort, there isn't much more that we will be willing to do for you.

All that you have shown us is that you can use cut with space as a delimiter to select part of an input line. Could you use cut with a different delimiter to get rid of the [?

What tools are you allowed to use for this assignment? You have shown us cut and we assume that you can use some shell (but we don't know which shell). You have suggestions to use GNU date and awk. Are these available for this assignment? Can you use a 1993 or later version of ksh (which can also perform simple calculations to get the date 10 days ago)?

Are you looking for a date 14 days ago to the second? Or, are you looking for a date starting at midnight almost 14 days ago? Whether or not you can use the date utility depends on what operating system and shell you're using?

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.

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category textutil
       of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have for
       either package and/or documentation.
