Below is rough outline :

1. Call script with few parameters like " -firstparam One -secondparam Two"
2. In script execute a unix command lets say "cat example.txt". Original output is -
This is line number 1
This is line number 2

3. Replace data in output -
1 is replaced by One and 2 by Two

4. Displays final output -
This is line number One
This is line number Two

I hope I am clear enough

xsil2graphics

XSIL2GRAPHICS(1)					User Contributed Perl Documentation					  XSIL2GRAPHICS(1)

NAME

       xsil2graphics - generate scripts to load xsil output data files

SYNOPSIS

       xsil2graphics [options] <xsil_file>

DESCRIPTION

       Utility program bundled with xmds, used to generate scripts that load simulation output data into either matlab (http://www.mathworks.com)
       or scilab (http://www.scilab.org), which are then used to manipulate the results further if necessary and then to present the results
       graphically.

       Matlab

       To generate a matlab m-file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics data_file.xsil

       or

       bash$ xsil2graphics --matlab data_file.xsil

       Then at the matlab command prompt:

       >> data_file

       Scilab

       To generate a scilab script file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics --scilab data_file.xsil

       Then at the scilab command prompt:

       --> exec('data_file.sci')

OPTIONS

       -m, --matlab generate matlab m-file script to load data from the xsil data file (the default option)

       -s, -scilab generate scilab script file to load data from the xsil data file

       -o, --outfile <out_file> specify an alternative output script filename to the default which is the input xsil filename with the .xsil
       extension changed to either .m for the matlab m-file or .sci for the scilab script file

EXAMPLES

       bash$ xsil2graphics nlse.xsil

       Generates the output nlse.m to load the data into matlab

       bash$ xsil2graphics -m nlse.xsil

       Also generates the output nlse.m but explicitly sets matlab to be the output format

       bash$ xsil2graphics --scilab nlse.xsil

       Generates the output nlse.sci to load the data into scilab

       bash$ xsil2graphics --outfile nlse_new.m nlse.xsil

       Generates the output nlse_new.m to load the data into matlab
