The Unix File System has the job of maintain all the data which is stored in the .
The data which is maintained includes programs, documents, databases, and .
textfiles. A file in Unix basically refers to the source of input or target of output, .
not just the place where the data is saved. The file itself can be read or be written on .
to. The Unix File System consists of three types of Unix files, text and binary files, .
directories and subdirectories, and special more specific directories. .
The three main types of Unix Files are ordinary files, directories, and special .
files. The ordinary file is just something which contains data which can be stored into .
the computer or something that can be written on. These are the more common files in .
which the user works with on a daily basis. The second file is a directory. The .
directory hold information that is used to organized and helps you access other files. .
The directory is stored on a disk and you don't create the directory yourself it is made .
for you and Unix does all the work. The last type of file is a special file or device .
file. This is a internal representation of a physical device. This file helps you send .
data using things like the keyboard, the screen, the printer, or the disk drive. .
Ordinary files are divided into two different categories: text files or binary .
files. Text files are the ones that contain letters in which you can read. Text files .
hold documents, memos, shell scripts, and notes. Binary files on the other hand are just .
number primarily the number '1' or '0'. These files contain non-textual data like .
pictures. Binary files start to make sense when they are processed by a program. The .
distinction between the text file and the binary file is when you can display the text .
file without having to using a program to process it for the user. .
In the real world or on the computer we use directories and subdirectories to .
organize our lives and our computers.
