Listing The file data.txt has the following structure:
Item1	Item2	...	ItemN
------------------------------------------------
Value11	Value21	...	ValueN1
Value12	Value22	...	ValueN2
:		:			:
Value1M	Value2M	...	ValueNM

Create a script that displays the information from the file data.txt
sorted by some criteria. Your script should have the following input
parameters:
listing -h -ilist -olist -ffile
-h displays help
-ilist, list defines criteria for sorting,
-olist, list defines which values will be displayed on the output,
-ffile, name of the input file.

Example
listing -i3,4 -o2,1 -fstudents.txt
file students.txt has the following contents
Surname 	Name	Class	Group
---------------------------------------
Novak		Petr	3	24
Dvorak		Jiri	3	24
Kovarikova	Lenka	3	23
Michalek	Karel	4	12
Cesilko		Mirek	3	23

The script listing displays
Class 3
Group 23
Lenka Kovarikova
Mirek Cesilko
Group 24
Petr Novak
Jiri Dvorak
Class 4
Group 12
Karel Michalek

[rest of homework assignment snipped]

You're in luck!

All your questions have already been answered in the
comp.unix.shell newsgroup. If you search the archives at
<http://groups.google.com/groups?group=comp.unix.shell>, you'll
find everything you need.

If you need more help, post the problem sections of your script to
the comp.unix.shell newsgroup. Be sure to explain exactly what is
going wrong (cut and paste error messages and incorrect output).
