Bob,

In Unix everything is a file... regular files, links, directories as well as the block and character special devices.  These entities you are seeing have a specific purpose to keep the Unix Operating system functioning.

Now, the /bin/ls binary has functionality that allows colorization based upon file type, and other factors.  Yes, like you, I typically work in listings that are black and white for ease of viewing.

The block device for /dev/sdb is used by a driver in the kernel to access that disk drive.  /dev/sdb1, for example, would be the first partition on that disk drive, etc...

Why are you worried about these?

Are you saying that the "b" is merely to control the color in a listing?
I view everything in black and white.

Does it have any other effect?

Is there a mknod command to remove it, the man page does not make it
clear to me.

Thanks for responding.

Bob
