NAME
Chj::IO::Command
SYNOPSIS
use Chj::IO::Command;
# my $mail = Chj::IO::Command->new_out("sendmail","-t"); or:
# my $mail = Chj::IO::Command->new_writer("sendmail","-t"); or:
my $mail = Chj::IO::Command->new_receiver("sendmail","-t");
warn "sendmail has pid ".$mail->pid;
$mail->xprint("From:..\nTo:..\n\n...");
my $exitcode = $mail->xfinish;
# my $date = Chj::IO::Command->new_in("date")->xcontent;
# my $date = Chj::IO::Command->new_reader("date")->xcontent;
my $date = Chj::IO::Command->new_sender("date")->xcontent;
# there's also ->new_err, which allows to gather errors
# or catch stdout and stderr both together:
my $str = Chj::IO::Command->new_combinedsender("foo","bar","baz")->xcontent;
DESCRIPTION
Launches external commands with input or output pipes. Inherits from Chj::IO::Pipe.
There is no support for multiple pipes to the same process.
NOTE
'new_in' does mean input from the view of the main process. May be a bit confusing, since it's stdout of the subprocess. Same thing for 'new_out'. Maybe the aliases 'new_reader' and 'new_writer' are a bit less confusing (true?).
