CLILSTORE Unit 14: Introduction to Shell Programming

CLILSTORE UNIT 14: Introduction to Shell Programming

Introduction

This Unit is included in the subject “Single-user Operating Systems”, in the first year of Microcomputer Systems and Networks vocational training degree.

The purpose of this Unit is to give students a general view of scripting and use of shell. To reach this purpose, we will begin with the different types of shell, syntax and control structures.

Furthermore, we will see how use the software cron to to schedule jobs (commands or shell scripts).
 

Aims

The aims of the unit are:

• To introduce the concept of Scripting.
• To understand the importance of scripts in the administration of operating systems.
• To know actual situation of Scripting in OS.
• To distinguish between the different types of execution of scripts.
• To list the different control structures in scripting.
• To know the scripting syntax.
• To use correctly expressions, vocabulary and structures of the language.
• To exchange ideas in English between the students (to promote the exchange of knowledge).

Learning outcomes and key competences

The skills and competencies that students are expected to acquire are:

To be able to:

• Identify the different types of scripts in operating systems.
• Describe the different scripts execution and their differences.
• Typify the different control structures in scripting.
• Create a basic script.
• Explain the importance of scripting in administration.
• Communicate correctly in English with other students and with the teacher.

 A scripting or         is a programming language supports scripts           written for a special run-time environment                     the of tasks that could alternatively be one-by-one by a human operator. Scripting                   are often (rather than compiled). Primitives are usually the                   tasks API calls, and the allows them to be into more                   programs. Environments that can be                   scripting include software                  , web pages within a web , usage of the shells of                   (OS), embedded , as well as numerous games. A scripting language can                   as a domain-specific language for a particular environment; the case of scripting an application, it is also as an extension language. Scripting languages are also sometimes to as very high-level programming , as they operate a high level of abstraction, or as                   languages, for job control languages on mainframes.
