This is very simple but I am not able to make it work..I have
a string and I want to get only the fourth field which
is delimited by space (although the first field may or may not have space before it
before it starts..I want to get the fourth field as
fast as possible as I have to do it many times..
$_="one two three four five six";
#it may be also be $abc=" one two three four five six"
print "\n the fourth field is $fieldfour \n";
but I am not ablre to get it..
