The only way I know of to pass command line arguments into awk is by
defining them as variables in an assign statement on the awk command line, ie

awk -f awkfile arg1=$1 arg2=$2 inputfile

will assign $1 to arg1, and $2 to arg2, inside the body of the awk program. It
is not possible to assign variable values in this manner to variables that
are used inside an action associated with the BEGIN pattern.

I am not sure how to do it with sed.
