DAY 5 APRIL 2026 DEVOPS Batch VIDEO | LINUX - SHELL SCRIPTING

Preethi conducted a training session on shell scripting and SSH, covering the basics of creating shell scripts, variables, conditional statements, and file operations. She demonstrated how to create and execute shell scripts with proper permissions, explained the use of positional parameters, and showed examples of using if-else statements and loops. The session also covered SSH (Secure Shell) concepts, including key-based authentication and connecting to remote servers using private and public key pairs. Preethi emphasized that while shell scripting is useful for basic automation, modern DevOps practices often use configuration management tools instead of deep shell scripting. The session concluded with a discussion about hands-on practice completion and next steps for learning Jenkins and CI/CD pipelines.
