Node Creation
Nodes are created by the mknod system call. The command-line program for creating nodes has the same name. Nodes can be moved or deleted by the usual filesystem system calls (rename, unlink) and commands (mv, rm). When passed the option -R or -a while copying a device node, the cp -l command creates a new device node with the same attributes of the original.
Some Unix versions include a script named makedev or MAKEDEV to create all necessary devices in the directory /dev. It only makes sense on systems whose devices are statically assigned major numbers (e.g. by means of hardcoding it in their kernel module).

Famous quotes containing the word creation:
“There have been heroes for whom this world seemed expressly prepared, as if creation had at last succeeded; whose daily life was the stuff of which our dreams are made, and whose presence enhanced the beauty and ampleness of Nature herself.”
—Henry David Thoreau (1817–1862)
