However, the shell is a complex program, and many of its more esoteric features can only be hinted at here. Issuing Commands The shell program requests commands from the user, decodes them, and communicates the user's wishes to the kernel. Practically all communication between the kernel and the user is handled by way of the shell. Its name was chosen to imply that the command decoder program surrounds the kernel, isolating it from the outside world. While the shell facilitates user access to the kernel, it also serves to separate the two, so the user can never readily tell just exactly what the kernel actually does.
They are made easy to find by name by creating an additional file called a directory, which shows where to find the individual files. A directory is simply a file which contains the file names and their physical addresses on the device. Directories have a strictly prescribed internal structure, for they must be accessible to quite a few internal system routines; but there is no physical difference at all between a directory and any ordinary file. Every directory is itself a file and is stored on disk like any other file.
When users list the directory contents, which they normally do by means of the Ls command, this special entry is suppressed to avoid clutter and confusion, unless the user specifically requests that it be made visible. Directory Hierarchies Since a directory is a file, it is readily possible to construct directories of directories. In fact, most Unix systems assign a personal directory to each user and list that directory as an entry in a directory of user directories, which is in tum an entry in a system directory.
