Does mkfifo simply not work with Cygwin? A simple set of commands such as
$ mkfifo my_pipe
$ echo "1234" > my_pipe
just causes the terminal to sit forever with the cursor blinking. Am I “doing it wrong”?
No, you’re not doing anything wrong with either of those commands, it’s just your expectations are a little off.
What you’re missing is something at the other end of that pipe, reading that data. This apparent hanging happens in Linux as well, so it’s not a CygWin problem (or any sort of problem, really).
Just open up another window and enter:
and you’ll see the data appear, followed by the original
echocompleting.
