Operating Systems & Shell Scripting
(Linux/Unix & Automation)
This comprehensive program provides in-depth training on operating systems concepts, Linux/Unix environments, and shell scripting for automation. Students will gain a strong understanding of OS fundamentals, work extensively with the command-line interface, master file and process management, and learn to write efficient shell scripts. The course combines theory with hands-on labs, enabling learners to develop practical skills in Linux/Unix administration, automation, and real-world system tasks.
(Duration: 90+ hours)
