FIFOs are created using the
$ mkfifo test
FIFOs provide a
named pipe to shuttle data from one place to another. If we create a FIFO and send some data to it, it will remain blocked forever, until a command tries to read from it. If you are familiar with golang and golang channels, that’s an Unbuffered/synchronous channel. Unbuffered channel blocks until there is a receiver receiving from a channel.
named pipes are very interesting and can be used in some interesting ways.
