Study guide
In this lab you install operating systems, use virtualisation to install an OS on a virtual machine, practise Linux file and directory commands (cd, ls, cp, mkdir, rmdir, cat), disk space commands, process management (pipes, background jobs, priority, ps, kill), text commands (grep, find, sort) and shell programming with conditions, loops, case statements, parameters, variables and task automation. Practise the commands in a real terminal, not only on paper.
Why Software Lab-IV (Operating Systems) Matters
Linux and shell scripting are essential for developers, system administrators and cloud engineers, and are tested in most DevOps and sysadmin interviews.
How to Prepare for Software Lab-IV (Operating Systems)
- Use a virtual machine so you can experiment safely.
- Write small shell scripts to automate tasks you do repeatedly.
- Learn grep, find and sort well; they are used constantly.
