Need to pass shell arguments into Nawk/awk

Hi,

I am in critical need of help, Thanks a ton for your help.

I need to know how to pass the shell argument into nawk code in AIX. so that my file gets passed into that awk script and it can execute it part.

To be detail, i have more than 100 files and in those files a particular field need t o encrypt. i have a nawk script which does that part, I will share the layout here.

Code:

nawk -F"<delimiter>"'{
if (FILENAME="Mapping_file")
{
map[$1]=$2
}
else of (FILENAME = "file1")
{
k=1
while (k <= "Need to pass second argument from shell")
{
<code to encrypt>
}
}
} Mapping_file file1

I am calling this script (a.ksh) from another main script and need to pass two arguemnts (file1 in above code --> file name should the first arguemnt) and second argument in while statement

My script execution should be like this

ksh a.ksh <filename> <length> > OUTPUTFILE

finally my code should like this

Code:

nawk -F"<delimiter>"'{
if (FILENAME="Mapping_file")
{
map[$1]=$2
}
else of (FILENAME = "<filename>")
{
k=1
while (k <= "<length>")
{
<code to encrypt>
}
}
} Mapping_file <filename>

Your help on early is much appreciated. Please help me as I m in desperate need of this solution.
