• Pipe an infinite stream to internal loop?

  - by Sh3ljohn

  I've seen a lot of things about redirecting stdout to a TCP socket, but no real example of how to do it in practice, specifically when the output stream generated by the first "command" never ends.

  I'm trying to pipe some data from a Bash pipe into a Bash variable using the read command, like this: $ echo "Alexander the Grape" | read quot $ echo $quot $ But quot is empty.
