Synopsis:

Unix-like operating systems represent a large family mostly open-source codes that kept bringing during the history of computers efficient innovative functions of multiuser operating systems for computers and their networks and clusters. The most popular OS today, Android, has a unix kernel. Students get overview of basic properties of this OS family, such as processes and threads, access rights and user identity, filters, or handling files in a file system. They learn to use practically these systems at the level of advanced users who are not only able to utilize powerful system tools that are available to users, but are also able to automatize routine agenda using the unix scripting interface, called shell.

Requirements:

Elementary GUI interaction.

Syllabus of lectures:

1. History and architecture of Unix-like operating systems, basic components of computer systems, secure remote access.

2. [2] Shell interface, command line processing, command executions and their parameters, special characters.

4. File systems and tools for handling files.

5. Text filters and further tools for text processing.

6. Regular expressions and their applications.

7. Text transformations, the sed and awk languages.

8. [2] Program return code, shell control constructs, arithmetic calculations, processing of script parameters.

10. Process and user identity and access rights.

11. Searching of files, compression and archiving.

12. Processes and threads, interprocess communication.

13. Shell jobs and their scheduling.

Syllabus of tutorials:

1. Introduction. GUI. Basic Unix commands. Introduction to shell, the vi editor. Basic commands for working with files and directories. Standard process inputs and outputs. Filters. Regular expressions. grep command. sed and awk commands. Access rights, find command, data backup and data compression.

2. Processes, exit code, test command. Variables, shell control commands, command blocks, functions, numeric computations. User input, processing flags, writing and debugging scripts, task scheduling. Shell scripting, consultations. Test. Assessment.
