Overview

This course provides an introduction to Unix/Linux and the use of the operating system commands. The course would also provide a good refresher to those returning to Unix/Linux after a long time on other platforms, and to those whose experience of Unix/Linux was not acquired through formal training and who wish to fill in gaps in their knowledge.

Prerequisites

The course would be suitable for anyone who needs to use Unix/Linux as a data-processing platform or those who support Unix-based applications and users. It would also give a useful introduction to anyone who needs to learn how to administer a Unix/Linux system, although administration is outside the scope of this course.

Delegates will learn how to

• Use features of the UNIX shell to customise their working environment
• Create, copy and move files and directories
• Secure files and directories using permissions
• Save the results of commands into a file
• Logon to a Unix system and use the korn shell command interface to run commands and locate and examine files
• Move around the UNIX filestore using full and partial pathnames
• Use features of the UNIX shell to combine commands using pipes

Outline

INTRODUCTION AND HISTORY

What does Unix do? Why Unix is useful. A brief history of Unix and why there are different flavours of Unix

BASIC UNIX COMMANDS

Logging-in and entering commands, types of user (user/superuser) and their capabilities, structure of the passwd file and how to read it, some useful identification commands (id/who/who am I), commands, options and arguments – how to create a command-line, listing files, reading files, finding the date and time, logging out

UNIX FILE SYSTEM STRUCTURE

Logical file system, root directory (/), standard Unix directory structure, navigating the directories – the cd command, pathnames (absolute vs relative), creating and removing directories, copying, renaming and deleting files

UNIX SHELLS (PRIMARILY KORN)

Bourne/C/Korn/Bash, general features of interactive shells, command line processing, internal vs external commands, identifying commands with the type command, wildcards and special characters, quoting text and special characters

EDITING WITH VI

Why learn vi? vi modes, vi cursor keys, vi insert commands, vi delete/cut commands, vi copy/paste commands, vi change commands, vi search and replace commands, vi file commands, configuring vi

SHELL CONFIGURATION

Aliasing commands, command history and command editing, sub(child) shells, environment (aliases/variables/shell options), shell variables (PATH/HOME/PWD/PS1), variables (local/exported), variables and quotes, command substitution, arithmetic substitution, configuration files (/etc/profile, .profile), the ENV variable and .kshrc

INPUT AND OUTPUT DATA STREAMS

Unix processes and stdin/stdout/stderr, redirection of stdout, redirection of stderr, redirection of both stdout and stderr, redirection of stdin, here-documents as an alternative to redirection from files, opening additional data streams, using additional data streams

PIPES AND DATA MANIPULATION

What is a pipe? Pipes vs redirection, some simple pipelines, some more complex pipelines

BASIC SHELL SCRIPTS

Shell as a programming language, #! (hashbang) header, positional parameters, if/then/else construct, test command, read command, loops (for/while/until)
