/dev/initctl .. What is this device file for.
I was just looking at the device files in /dev file system and I observe some special device file named /dev/initctl. When I execute the command
ll /dev/initctl ,
it is displaying me the following output
prw------- 1 root root 0 Nov 5 23:47 initctl.
Here, I would like to know the permissions i.e. prw----, what does the 'p' refers to. Moreover, what this device file is for?
