mknod: Create a FIFO (queue) device.

mknod

$ sudo mknod ${path-to-device_file} p

try on your machine

This command is used to create a named pipe (also known as a FIFO) using the mknod utility in Linux.

Here is a breakdown of the command:

sudo: This is a command used to execute another command with administrative privileges. By using "sudo", you are running the mknod command as the superuser or root user, which typically has the necessary permissions to create device files.
mknod: This is the command used to create a device file, including named pipes. It is typically used to create character and block special files, but in this case, the "p" option is specified to create a named pipe.
${path-to-device_file}: This is a placeholder that should be replaced with the actual path and filename for the named pipe you want to create. The path should specify the location where you want to create the named pipe, and the filename should be the name you want to assign to the pipe file.
p: This is an option passed to the mknod command to specify that a named pipe should be created. In Linux, named pipes are denoted by the 'p' character.

Overall, this command creates a named pipe file at the specified path and filename, allowing different processes to communicate with each other using the pipe for interprocess communication.
