html - 如何使用awk根据其他字段求和字段

Question

在我的评估中，我被要求编写一个仅使用 bash 命令的 shell 脚本和另一个仅使用 SQL 查询的 shell 脚本。这些脚本应该执行以下操作:1.清理.csv文件中的数据(暂时不重要)2. 根据性别总结收入3.制作一个简单的HTML表格

我已经使 SQL 查询生成了正确的数字和 HTML 文件，但在其他 bash 命令的帮助下。对于应该只包含 bash 命令的文件，我能够得到该表，但其中一个数字是错误的。

我对 bash 脚本和 SQL 查询还很陌生，所以代码不是很优化。

以下是示例输入的简化版本: CSV input

对于 SQL 查询，仅文件这是我目前的代码(生成正确的数字和正确的表格):

python3 csv2sqlite.py --table-name test_table --input table.csv --output table.sqlite


echo -e '<TABLE BORDER = "1">
<TR><TH>Gender</TH>
<TH>Total Amount [$]</TH>
</TR>' >> tmp1.txt
sqlite3 biopics.sqlite 'SELECT subject_sex,SUM(earnings) FROM table \
GROUP BY subject_sex;' -html > tmp2.txt
cat tmp2.txt >> tmp1.txt
echo '</TABLE>' >> tmp1.txt

cp tmp1.txt $1

cat $1

rm tmp1.txt tmp2.txt

到目前为止，对于 bash 唯一文件，这是我的代码:

echo -e '<TABLE BORDER = "1">
<TR><TH>Gender</TH>
<TH>Total Amount [$]</TH>
</TR>' >> tmp1.txt
awk -F ',' '{for (i=1;i<=NF;i++) 
        if ($1) 
            a[$13] += $5} END{for (i in a) printf("<TR><TD> %s </TD><TD> %i </TD></TR>\n", i, a[i])}' table.csv | sort | head -2 > tmp2.txt
cat tmp2.txt >> tmp1.txt
echo -e "</TABLE>" >>  tmp1.txt

cp tmp1.txt $1

cat $1

rm tmp1.txt tmp2.txt

预期的输出应该是这样的:

<TABLE BORDER = "1">
<TR><TH>Gender</TH>
<TH>Total Amount [$]</TH>
</TR>
<TR><TD>Female</TD>
<TD>8480000.0</TD>
</TR>
<TR><TD>Male</TD>
<TD>455947000.0</TD>
</TR>
</TABLE>

提前致谢!

#! /bin/bash

awk -F, '{
    if (NR != 1)
    {
        if (sum[$13] == "")
        {
            sum[$13]=0
        }
        sum[$13]+=$5
    }
}
END {
    print "<TABLE BORDER = \"1\">"
    print "<TR><TH>Gender</TH><TH>Total Amount [$]</TH></TR>" 
    for ( gender in sum )
    {
        print "<TR><TD>"gender"</TD>", "<TD>"sum[gender]"</TD></TR>"
    }
    print "</TABLE>"
}' table.csv

如果适合您，请在此处尝试。

更新:

我从您的评论中了解到，您希望根据总和对数据进行排序。

#! /bin/bash

awk -F, -v OFS=, '{
    if (NR != 1)
    {
        if (sum[$13] == "")
        {
            sum[$13]=0
        }
        sum[$13]+=$5
    }
}
END {
    for ( gender in sum )
    {
        print gender, sum[gender]
    }
}' table.csv | sort -nk 2,2 |

    awk -v firstline="$(sed -n '1p' table.csv)" '{
        printrow($0)
    }

    BEGIN {
        split(firstline, headers, ",")
        print "<html>"
        print "<TABLE BORDER = "1">"
        printrow(headers[5]","headers[13], 1)
    }
    END {
        print "</table>"
        print "</html>"
    }
    function printrow(row, flag) 
    {
        # if flag == 0 or null "<TD>" else "<TH>"
        len = split(row, cells, ",")
        print "<TR>"
        for (i = 1 ; i <= len ; ++i)
        {
            if (!flag)
                print "<TD>"cells[i]"</TD>"
            else
                print "<TH>"cells[i]"</TH>"
        }
        print "</TR>"
    }'

以上，我基本上把你需要的分成了2个模块，

---

操作表中的数据:

1) 整理表格

2) 根据第 2 列对数据进行排序。这个我应该在第一个 awk 脚本本身中完成，但这样会更短一些。

---

将其转换为 html 表格:

第二个 awk 脚本接收第一个脚本的输出。它设置标题和标签。

---

我觉得这样更模块化。这只会让修改变得更容易。第一个用于数据操作的脚本，第二个用于放置标题或标签。

我个人喜欢的是为第二个 awk 脚本提供它自己的可执行文件。现在只需使用第一个脚本进行数据操作，然后将其传递给另一个脚本来设置 html 标签和标题。

可能有更好的选择，我建议了我所知道的最好的选择。
