It offers a more readable and efficient way to execute commands based on pattern matching, making your shell scripts easier to maintain and understand.Here, we will better understand the case command in Linux, learning about its syntax, examples, and options.Syntaxcase WORD in [PATTERN [| PATTERN]...) COMMANDS ;;]... esacwhere, WORD: The variable or value that you want to match against different patterns.PATTERN: One or more patterns to compare against the WORD.
