Question

I rewrite my old code in new style, like below:

#old style open(FD,'file');  #new style $fh = IO::File->new('file','r'); 

Files are ok, but I don’t know how to open pipes.

# read from pipes. open(PIPE,'some_program |');  # write to pipes. open(PIPE,'| some_program'); 

How to treat pipes in OO Style IO?

adding:
thanks Jonathan, it’s fine.

# read from pipes. $pipe = IO::Pipe->new; $pipe->reader('some_program'); $data = <$pipe>;  # write from pipes. $pipe = IO::Pipe->new; $pipe->writer('some_program'); print $pipe 'foo,bar,baz'; 

Answer 1

You should check out IO::Pipe and FileHandle.
