Help with this Script!

So I'm trying to sort the following:
The order should be ascending by AuctionID, and then within that descending by Bid and then within that ascending by BidDateTime.
So it can be output to another file.

Here is the actually file I'm trying to sort:

"AuctionID","UserID","BidderRating","Bid","BidDateTime"
1070387924,"rmichaelll",46,407.00,2/12/2002 14:07:44
1070387924,"decocloxcolektor",155,402.00,2/12/2002 14:07:28
1070387924,"markartz",6,350.00,2/12/2002 11:11:52
1070387924,"markartz",6,275.00,2/12/2002 1:23:19
1070387924,"mcintron55@aol.com",179,265.00,2/11/2002 16:17:12
1070387924,"jellyroll33",325,250.00,2/5/2002 14:49:17
1070387924,"markartz",6,250.00,2/9/2002 14:56:53
1070387924,"jarmst1626@aol.com",14,200.00,2/2/2002 21:25:06

This is what I have so far:

sed '1d' ebay.dat | sort -t, -k1n -k4nr -k5n > ebay_sort.dat

Now I what to ask Ask the user to enter the auction id and use grep to get the lines stating the auction id.

Once found, cut the fields.

Could someone please point me in the right direction?

Once found, cut the fields.

What is this supposed to mean? And what exactly is the problem? Don't you know how to read user input?

In this case, I would suggest that you go to the course instructor / professor and explain that you don't understand how to solve the homework. Honesty is the best policy.
