#!/bin/bashread -p "please input a number: " a
b=$[ $a%2 ]case $b in
1) echo "the number is odd "
;;
0) echo "the number is even"
;;
*) echo "it is not a odd or even"
;;
esac |
注：*) echo "it is not a odd or even",只是语句完善，因为输入无论数字还是字符串不是0就是1
[root@Linux9 ~]# sh case.sh
please input a number: 2333
the number is odd
[root@Linux9 ~]# sh case.sh
please input a number: 6666
the number is even
