-> To create a new device file -> To create a new device file
Use: Use:
mknod <device-name> <type of device 'c' or 'b'> <major-num> <minor-num> mknod <device-name> <type of device 'c' or 'b'> <major-num> <minor-num>
-> /dev/*:
this file basically contains virtual files which act as a
interface between the device driver in kernel space and
the user space, which allow the control of the device from
user space.
-> The link between the driver and the device file is made over
the major and minor number of the device file rather than
name of the device file. So, if I associate a custom made
device file with driver using same major and minor number.
I can access the same device using that file.
