I have the following code which generates a specific output. 
my @result = (`cmd to get result`) ;
   foreach $result (@result) {
            @streams = ;
            @spaces = ;
          }

[download]
The command to get result has the following output 
ws.abc.dsfsfsfwerfrwef std 13232
ws.dfsdferferfregregrgr std 99868 Y
ws.abc.asddwefewfewfewf std 45345
fwfrwfrefergegregerefds std 36754 Y
ws.abc.fferfergregrfreg std 45435

I would like to get the 1st word (before space) and which has "Y" at the ending to an array @streams and for rest of lines only 1st word (before space) to array @spaces like shown below.
@streams=(fwfrwfrefergegregerefds, ws.dfsdferferfregregrgr)
@spaces=(ws.abc.dsfsfsfwerfrwef, ws.abc.asddwefewfewfewf, ws.abc.fferfergregrfreg)
How can I achieve it?
