system v backticks

[Keenan, Greg John (Greg)** CTR **]

Hi,

Can someone explain the difference between backticks and system when
evaluated in this if statement:


sub getDate {
 print "start date\n";
 if ( system("/bin/date") ) {
   print "can't get date\n";
   exit(2);
 }
 print "finish date\n";
}

Returns the following:

start date
Thu Jul 28 12:13:59 EST 2005
finish date



While this:

sub getDate {
 print "start date\n";
 if ( `/bin/date` ) {
   print "can't get date\n";
   exit(2);
 }
 print "finish date\n";
}

Returns this:

start date
can't get date
