Hi,
system “mkfifo ttt”
pid = fork
exec (“cat < ttt”) if pid.nil?
exec (“exec cat < ttt”) if pid.nil?
I would expect only one process the real “cat process”, but apparently, ruby
spawned
a process and then a child process, which is the real one.
When you use redirection, ruby invokes /bin/sh and /bin/sh
forks to execute the command.
When you use redirection, ruby invokes /bin/sh and /bin/sh
forks to execute the command.
Is there any chance Ruby will eventually have its `own’ OS hooks so
that it won’t have to do the above?

Though I’m not sure what you mean by “OS hooks”, do you want to
avoid running /bin/sh?
If so, you need to redirect by yourself in the child process
now.
unless pid = fork
STDIN.reopen(open(“ttt”))
exec(“cat”)
end
