Please note that Scrutinizer's code assume that for a certain $1, the first value in the second column is 1, according to the example you gave.

If it happen that you have an input file like :
Code:
awex1   1
awex1   2
awex1   3
assww   5
ader34   1
ader34   2

And if you expect the output:
Code:
assww   5

You could then go for the line i proposed in post #2
