UNIX

Introduction to Linux

Unix is a multi-user, multi-tasking operating system.

You can have many users logged into a system simultaneously, each running many programs.

It's the kernel's job to keep each process and user separate and to regulate access to system hardware, including cpu, memory, disk and other I/O devices.

History of UNIX

Introduction to Linux

1973 Unix is re-written mostly in C, a new language developed by Dennis Ritchie.

Being written in this high-level language greatly decreased the effort needed to port it to new machines.

History of UNIX

Introduction to Linux

1977 There were about 500 Unix sites world-wide.

1980 BSD 4.1 (Berkeley Software Development)

1983 SunOS, BSD 4.2, System V

1988 AT&T and Sun Microsystems jointly develop System V Release 4 (SVR4). This later developed into UnixWare and Solaris 2.

1991 Linux was originated.

UNIX Structure

Introduction to Linux

File System

Introduction to Linux

The Unix file system looks like an inverted tree structure.

You start with the root directory, denoted by /, at the top and work down through sub-directories underneath it.

File System

Introduction to Linux

Each node is either a file or a directory of files, where the latter can contain other files and directories.

You specify a file or directory by its path name, either the full, or absolute, path name or the one relative to a location.

The full path name starts with the root, /, and follows the branches of the file system, each separated by /, until you reach the desired file, e.g.:

/home/condron/source/xntp
