case conditionals like the same multi-branch if statement (refer to the previous article), but it looks more formal than if multi-branch conditional sentence.
conditional case less and is more suitable for a character string of fixed variables.
case syntax how to write it? as follows:
# Variable = variable
# Value = value
case "variable" in value 1) Command 1 ;; value 2) Command 2 ;; *) Command 3 ;; esac |
case "variable" in value 1) Command 1 ;; value 2) Command 2 ;; *) Command 3 ;; esac |
Conditional execution flow case is kind of how it? Above:
