1.计算测试:
注:分别输入5和1代表5月1日
注:此为计算结果
2.脚本如下:(9.11.12行-c后面的列数需要按照你本机date显示的去修改,下面参数有注释)

3,注释
if | -eq等于 | -ne不等于 | -gt大于 | -lt小于 | -le小于等于 | -ge大于等于 | =相等 | !=不等 | -z空串 -n非空串 |
expr | +加 | -减 | \*乘 | /除 | %取余数 |
declare -i | 声明( -i参数为数值) 这里表达声明后面的变量为数值 |
echo “” | 输出到屏幕(``里可以执行命令) |
read | 基本读取 (-p可以跟多个变量) |
cut | 文本处理-取值命令 |
cut -c7-13 | -c指定列 这里是7-13列(本文7-13列是月和日,7-8是月,11-12是日,请在你本机date查看日期修改相对列数) |
