Linux self-study _shell script case

Case can be replaced with if, the only difference is that when the variable has a fixed number of values, the syntax is relatively neat.

Example

A script used by enterprises to start some programs

Example One: VI apache.sh
#!/bin/sh
Case $ in
Start | begin)
/etc/init.d/httpd Start
         ;; 
Stop | end)
/etc/init.d/httpd Stop
         ;; 
         *) 
echo "Error input! " 
         ;; 
Esac
