问题描述
我用新样式重写了旧代码，如下所示:
I rewrite my old code in new style, like below:
#old style
open(FD,"file");
#new style
$fh = IO::File->new("file","r");
文件还可以，但是我不知道如何打开管道.
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");
如何在OO Style IO中处理管道?
