[turnersn]

Here is the basic script I want to pass 3 arguments into:<br><br>awk '{if(substr($0,position,length)==&quot;variable&quot {print $0}}' input file &gt; output file<br><br>I want to pass in the position, length, and variable at the command line when running this script?&nbsp;&nbsp;Any ideas.&nbsp;&nbsp;I have looked at ARGV & ARGC, but I have not been successful.
