command line argument vs. urlencode ?

Hi, Any one know why the "+" (plus sign) is not passed as argument to $argv when calling a php script from linux shell ? if this is not a bug, how do I pass a "+" as argument ? should I use urlencode/urldecode ? is that any php.ini variable to turn off this behavior ? try this and you will see : ---- teste.php---------- <?php foreach( $argv as $x ) printf("p: %s\n",$x); ?> --------------- call with : php test.php 123 xxx+yyyy
