perl redirection linux

sub cdevice{
     $p=$_[0];
     $s=$_[1];
     $q=$_[2];
     try {
         $device_create_cmd ="create type:NSR Device;media type:adv_file;name:$p;device access information:$p";
         system("echo $device_create_cmd > command.txt  ");
     } catch Error with {
         print "Error  " ;
         exit();     
     };
 }
 cdevice("/device1","raddh054","/device1");
 

this pl file is working fine on Windows but not on Linux because echo in Linux is not accepting spaces between the text !how do i resolve it
