i tried my script file 
open(TST, "test.log") or dir $!;

while (<TST>) {
     chomp;
     if (/start/ .. /end/) {
       s/.*(start.*end).*/$1/m;
       print "$_\n";
     }
}

i know why...cause it still read line by line even if you use range operator. so the $_ is like 
1.asdasd start asdsadsdasddasds sdasdas asdasdasdasd asdasdsa
2.asdasd asdasdasd end

[download]
two separate line in "while" and range operator can just be used to print 
start
adasd
asdasd
asdasd
asdas
end

my question is how to get that output? thank you!
