<p>Welcome to the age old headache of the shell programmer. Each utility can/will be in different locations among differing OS's, and their command switches and default output will certainly be different. I think this was a reason Perl became popular as a cross-OS scipting language, no?</p>
<p>Perhaps look into the <a href="http://www.perl.com/language/ppt/what.html">Perl Power Tools</a>, which are pure-Perl versions of many Unix utilities.</p><br>
