[Linux in 101 Days | Day 9.1] Linux Shell Architecture and Command Line Fundamentals
This video covers Linux shell architecture and command-line fundamentals, starting from a basic level. The shell's position between the user, system calls, kernel, and hardware is explained; fundamental concepts such as instruction interpretation, piping, I/O redirection, and environment variables are discussed. Different shell types such as Bash, sh, Zsh, ksh, and Fish Shell are compared; and the logic of repositories, EPEL, and CRB is explained through the example of Fish Shell installation on Rocky Linux. Furthermore, concepts such as login shell, non-login shell, interactive shell, non-interactive shell, and shell scripting are evaluated from a system administration perspective. This video is part of the 101 Days of Linux training series.
