Question

我的脚本会询问姓名，电话号码和出生日期，然后将这些详细信息修改为名为“birthday.csv”的逗号分隔值文件。

然后按出生日期对“birthday.csv”进行排序。然后显示新排序的文件。它还计算每个人的年龄和文件中的条目数。

我的问题是，它接收了所有信息，但在打印内容之前它不会对文件进行排序。

以下是代码：

a=0
while [ $a -lt 2 ];
do
    echo Please enter a first name
    read firstName
    echo Please enter last name
    read lastName
    echo Please enter phone number
    read phoneNumber
    echo Please enter date of birth - format dd/mm/yyyy
    read dob
    echo "$firstName,$lastName,$phoneNumber,$dob" >> Birthdays.csv
    echo If you would like to add another person press 1 or enter 2 to proceed
    read a
done

INPUT=./Birthdays.csv
OLDIFS=$IFS
IFS=","
[ -f ${INPUT} ] && while read Name Surname Telephone DOB
do
    birthMonth=${DOB:0:2}
    birthDay=${DOB:3:2}
    birthYear=${DOB:6:4}

    currentDate=`date +%d/%m/%Y`

    currentMonth=${currenDate:0:2}
    currentDay=${currentDate:3:2}
    currentYear=${currentDate:6:4}

    if [[ "$currentMonth" -lt "$birthMonth" ]] || [[ "$currentMonth" -eq "$birthMonth" && "$(currentDay)" -lt "$($birthDay)" ]]
    then
        let Age=currentYear-birthYear-1
    else
        let Age=currentYear-birthYear
    fi

    echo "Name : $Name"
    echo "Surname : $Surname"
    echo "Telephone : $Telephone"
    echo "DOB : $DOB"
    echo "Age : $Age"
    echo "##########################################"
done < $INPUT
IFS=$OLDIFS
    echo $DATE

exit 0;

我认为问题在于

if [[ "$currentMonth" -lt "$birthMonth" ]] || [[ "$currentMonth" -eq "$birthMonth" && "$(currentDay)" -lt "$($birthDay)" ]]
then
    let Age=currentYear-birthYear-1
else
    let Age=currentYear-birthYear
fi

但是我不确定是什么导致不排序？

Answer 1

首先删除“$（currentDay）”和“$（currentDay）”

周围的括号

Answer 2

你有一个错误，至少：

if [[ "$currentMonth" -lt "$birthMonth" ]] || [[ "$currentMonth" -eq "$birthMonth" && "$(currentDay)" -lt "$($birthDay)" ]]

"$(currentDay)"应该只是"$currentDay"而"$($birthDay)"应该只是"$birthDay"。

你这里也有一个错字：

currentMonth=${currenDate:0:2}

那应该是currentDate。将set -u放在脚本的顶部以捕获此类错误。

另外，就像Mat说的那样，我没有看到任何排序代码：）

此脚本不会按年龄正确排序
