shell指令碼菜單的建立

建立文本菜單建立菜單布局

root@wl-MS-7673:/home/wl/案頭/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表示不列印斷行符號       8    read -n1 option #讀取一個字元       9    echo ""  root@wl-MS-7673:/home/wl/案頭/shell# ./test1.sh Menu1.Display disk space2.Display logged on user3.Display memory usage0.Exit menuEnter option:1root@wl-MS-7673:/home/wl/案頭/shell# 

建立菜單函數

只需把上面的代碼用函數包起來即可

添加菜單邏輯添加對應的case即可
