To create FIFOs, we use the mkinfo command to create what appears to be a file (everything is a file in Linux). This file has a special property, though, which is different than normal files and also different from the pipes we had been previously using: the pipes, in this case, can allow for multiple readers and writers!
As with any file, you can also provide permissions using the -m flag such as this: -m a=rw, or use the mknod command (this isn't covered as it requires that you use a second command called chown to change permissions after creation).
