file

Hi all,

I have something to do that it must be finished before 4.00PM.
I want create a batch file with awk, grep or sed that keep all lines beginning with 'INSERT' and delete the other lines.
After this, i want replace a string "change)" by "servicechange)" when the 3rd word in the treated line is "donextsit".

I don't know how to do this before my deadline (4.00 PM). Please HELP ME!!

Thx for your answers.
And Sorry for my english ;)
