Linux Need to pass shell arguments into Nawk/awk
Thanks you all for quick resposne. sorry I think i m not clear with my initial query.

Scripts should run like this ": ksh encrypt.ksh <input file> <Length> > Outputfile

Inputfile = different files like file1, file2 etc..
length = varies from file 1 to file2 etc..

My current script:

Code:
nawk -F"<delimiter"'{
if (FILENAME=="MAPPINGS.TXT")
{
map{$1]=$2
}
if (FILENAME=="file1 or file2")
{
while (i <= $length(parameter from script) )
{
print i,
<using map, ecnrypt the values using substr funciton to a certain length>
}
i++;
print i; (remaining records in that line)
}' MAPPINGS.TXT file1 or file2 (1st shell argument)

MAPPINGS.TXT == a single file used for all files.
file1 or file2 = Shell script first parameter
length = Shell script second parameter

NOTE: My encrypt.ksh script only consists of nawk command, I need to pass shell arguments into that nawk script.

your help is much appreciated as I m in desperate need to complete this on priority.

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.

SEE ALSO

       shtool(1), which(1).
