- Create a character device:
sudo mknod {{path/to/device_file}} c {{major_device_number}} {{minor_device_number}}
- Create a FIFO (queue) device:
sudo mknod {{path/to/device_file}} p
- Create a device file with default SELinux security context:
sudo mknod -Z {{path/to/device_file}} {{type}} {{major_device_number}} {{minor_device_number}}
