Hi,
I need some suggestions howto do this. I was thinking of using a perl map but not sure whether its required. Need some help.
My input file looks like this:- 
253868    20    317    2628
253868    20    317    7294
256158    9    329    371
256158    9    329    86450
728481    1    353    1361
154664    7    440    449688
154664    7    440    563

My output should be like this:- 
253868    20    317    7294 
256158    9    329    86450
728481    1    353    1361
154664    7    440    449688

Want I want is that my key should be same but the value should be only the minimum and the maximum value.
Can you please suggest what will be the easiest way to get such an output.
Thanks
cowboy
