Unfortunately, this doesn't do quite what the original poster asked for. Consider [id://bart]'s code snippet above and plug it into yours:

$_ = 'FDR [62.10060.051-F] [62.10051.381] [this includes spaces!] 0 1 
+0';
($nobrackets = $_) =~ s/(\[|\])//g;
@feeder_line = split ' ', $nobrackets;

$\ = "\n";
print for @feeder_line;
__END__
FDR
62.10060.051-F
62.10051.381
this
includes
spaces!

N.B.: I have removed the mys because my ($nobrackets = $_) ... results in the error message Can't use global $_ in "my" at - line 1, near "= $_" (the correct syntax is (my $nobrackets = $_) ...
