A Crash Course In AWK

A Crash Course In AWK.

I use nawk (in most Linux distributions) instead of awk, and I highly recommend you learn how to pass an argument into (n)awk from a shell script using: -v x=arg1 -v y=arg2 where x and y are internal to the awk program and arg1 and arg2 are values from a shell script value, e.g. $var1 and $var2. Each argument passed into the (n)awk program requires a -v to precede it for as many args as you pass into the (n)awk program from the shell script.
