hi
if i want to know the words wich begins with "f" this is my code:

#!/usr/bin/perl
use strict;
use warnings;
$_="four fifth two frog left leaf fred wolf foul";
my @F=m/\bf.*?\b/g;
print "@F";
[download]

the result is "four fifth frog fred" this is correct.
but if i want to know the words which ends with "f": using the code:

$_="four fifth two frog left leaf fred wolf";
my @F=m/\b.*?f\b/g;
print "@F";
[download]

i get all the string "four fifth two frog left leaf fred wolf" and it must be "leaf wolf".
what is the right regex?
also i want to know the words wich does not begin with "f" but have at least one "f" in the remainder of the word:

$_="four fifth two frog left leaf fred wolf";
my @F=m/\b[^f].*?f.*?\b/g;
print "@F";
[download]

the result "fifth two frog left leaf fred wolf"
and it must be "left leaf wolf"
can someone please give me a hint on the right regex here
thanks
