Operating Systems provides a useful foundation for this course.
This course gives students who have already basic Unix/Linux experience some additional practical software-engineering knowledge: how to use the shell and related tools as an efficient working environment, how to automate routine tasks, and how version control and automated-build tools can help to avoid confusion and accidents, especially when working in teams. These are essential skills, both in industrial software development and student projects.
- Unix concepts. Brief review of Unix history and design philosophy, documentation, terminals, inter-process communication mechanisms and conventions, shell, command-line arguments, environment variables, file descriptors.
- Shell concepts. Program invocation, redirection, pipes, file-system navigation, argument expansion, quoting, job control, signals, process groups, variables, locale, history and alias functions, security considerations.
- Scripting. Plain-text formats, executables, #!, shell control structures and functions. Startup scripts.
- Text, file and networking tools. sed, grep, chmod, find, ssh, rsync, tar, zip, etc.
- Software development tools. C compiler, linker, debugger, make.
- Revision control systems. diff, patch, RCS, Subversion, git.
- Perl. Introduction to a powerful scripting and text manipulation language. [2 lectures]
At the end of the course students should
- be confident in performing routine user tasks on a POSIX system, understand command-line user-interface conventions and know how to find more detailed documentation;
- appreciate how simple tools can be combined to perform a large variety of tasks;
- be familiar with the most common tools, file formats and configuration practices;
- be able to understand, write, and maintain shell scripts and makefiles;
- appreciate how using revision control systems and fully automated build processes help to maintain reproducibility and audit trails during software development;
- know enough about basic development tools to be able to install, modify and debug C source code;
- have understood the main concepts of and gained initial experience in writing Perl scripts (excluding the facilities for object-oriented programming).
