shell脚本菜单的创建

创建文本菜单创建菜单布局

root@wl-MS-7673:/home/wl/桌面/shell# cat -n test1.sh 
     1	    #!/bin/bash  
     2	    echo -e "\t\tMenu"  
     3	    echo -e "1.\tDisplay disk space"  
     4	    echo -e "2.\tDisplay logged on user"  
     5	    echo -e "3.\tDisplay memory usage"  
     6	    echo -e "0.\tExit menu\n\n"  
     7	    echo -en "\t\tEnter option:" #-n表示不打印回车  
     8	    read -n1 option #读取一个字符  
     9	    echo ""  
root@wl-MS-7673:/home/wl/桌面/shell# ./test1.sh 
		Menu
1.	Display disk space
2.	Display logged on user
3.	Display memory usage
0.	Exit menu


		Enter option:1

创建菜单函数

只需把上面的代码用函数包起来即可

添加菜单逻辑添加对应的case即可

root@wl-MS-7673:/home/wl/桌面/shell# cat -n test2.sh 
     1	    #!/bin/bash  
     2	    option=""  
     3	    create_menu(){           
     4	        echo -e "\t\tMenu"  
     5	        echo -e "1.\tDisplay disk space"  
     6	        echo -e "2.\tDisplay logged on user"  
     7	        echo -e "3.\tDisplay memory usage"  
     8	        echo -e "0.\tExit menu\n\n"  
     9	        echo -en "\t\tEnter option:"  
    10	        read -n1 option  
    11	        echo ""
