How can I open a pipe both to and from a command?
The IPC::Open2 module (part of the standard perl distribution) is an
easy-to-use approach that internally uses pipe(), fork(), and exec() to do
the job.
Make sure you read the deadlock warnings in its documentation,
though (see IPC::Open2). See "Bidirectional Communication with Another
Process" in perlipc
and "Bidirectional Communication with Yourself" in perlipc
You may also use the IPC::Open3 module (part of the standard perl
distribution), but be warned that it has a different order of arguments
from IPC::Open2
(see IPC::Open3).
