Shell 循环并合并两个文本文件的脚本

我有两个.csv文件，我正试图通过脚本“倍增”出来。第一个文件是个人信息，基本上如下所示：

First Name, Last Name, Email, Phone
Sally,Davis,sdavis@nobody.com,555-555-5555
Tom,Smith,tsmith@nobody.com,555-555-1212

AccountID
1001
1002

First Name, Last Name, Email, Phone, AccountID
Sally,Davis,sdavis@nobody.com,555-555-5555, 1001
Tom,Smith,tsmith@nobody.com,555-555-1212, 1001
Sally,Davis,sdavis@nobody.com,555-555-5555, 1002
Tom,Smith,tsmith@nobody.com,555-555-1212, 1002

第二个文件是帐号，如下所示：

First Name, Last Name, Email, Phone
Sally,Davis,sdavis@nobody.com,555-555-5555
Tom,Smith,tsmith@nobody.com,555-555-1212

AccountID
1001
1002

First Name, Last Name, Email, Phone, AccountID
Sally,Davis,sdavis@nobody.com,555-555-5555, 1001
Tom,Smith,tsmith@nobody.com,555-555-1212, 1001
Sally,Davis,sdavis@nobody.com,555-555-5555, 1002
Tom,Smith,tsmith@nobody.com,555-555-1212, 1002

基本上，我想用每个帐户Id获取每个名称。因此，如果我在第一个文件中有10个名称，在第二个文件中有10个帐户Id，我应该在生成的文件中有100行，并使其如下所示：

First Name, Last Name, Email, Phone
Sally,Davis,sdavis@nobody.com,555-555-5555
Tom,Smith,tsmith@nobody.com,555-555-1212

AccountID
1001
1002

First Name, Last Name, Email, Phone, AccountID
Sally,Davis,sdavis@nobody.com,555-555-5555, 1001
Tom,Smith,tsmith@nobody.com,555-555-1212, 1001
Sally,Davis,sdavis@nobody.com,555-555-5555, 1002
Tom,Smith,tsmith@nobody.com,555-555-1212, 1002

任何帮助都将不胜感激

您只需为每个值编写一个for循环，通过其id计数重复，并附加描述，但顺序正好相反。

这是否有效？或者您是否尝试过这一点？

如果python适合您，下面是一个脚本：

def main():
    f1 = open("accounts.txt", "r")
    f1_total_lines = sum(1 for line in open('accounts.txt'))
    f2_total_lines = sum(1 for line in open('info.txt'))

    f1_line_counter = 1;
    f2_line_counter = 1;

    f3 = open("result.txt", "w")
    f3.write('First Name, Last Name, Email, Phone, AccountID\n')

    for line_account in f1.readlines():
        f2 = open("info.txt", "r")
        for line_info in f2.readlines():
            parsed_line_account = line_account
            parsed_line_info = line_info.rstrip() # we have to trim the newline character from every line from the 'info' file
            if f2_line_counter == f2_total_lines: # ...for every but the last line in the file (because it doesn't have a newline character)
                parsed_line_info = line_info
            f3.write(parsed_line_info + ',' + parsed_line_account)

            if f1_line_counter == f1_total_lines:
                f3.write('\n')

            f2_line_counter = f2_line_counter + 1

        f1_line_counter = f1_line_counter + 1
        f2_line_counter = 1 # reset the line counter to the first line

    f1.close()
    f2.close()
    f3.close()

if __name__ == '__main__':
    main()

我使用的文件如下：

info.txt

：

Sally,Davis,sdavis@nobody.com,555-555-555
Tom,Smith,tsmith@nobody.com,555-555-1212
John,Doe,jdoe@nobody.com,555-555-3333

1001
1002
1003

accounts.txt

：

Sally,Davis,sdavis@nobody.com,555-555-555
Tom,Smith,tsmith@nobody.com,555-555-1212
John,Doe,jdoe@nobody.com,555-555-3333

1001
1002
1003

如果您打算复制帐户ID

如果您打算将每个

帐户\u ID

添加到信息文件中的每个记录中，则可以使用简短的

awk

解决方案，例如

$ awk -F, '
    FNR==NR{a[i++]=$0}
    FNR!=NR{b[j++]=$0}
    END{print a[0] ", " b[0]
        for (k=1; k<i; k++)
            for (m=1; m<i; m++)
                print a[m] ", " b[k]}
' info id
First Name, Last Name, Email, Phone, AccountID
Sally,Davis,sdavis@nobody.com,555-555-5555, 1001
Tom,Smith,tsmith@nobody.com,555-555-1212, 1001
Sally,Davis,sdavis@nobody.com,555-555-5555, 1002
Tom,Smith,tsmith@nobody.com,555-555-1212, 1002

（注意：该

-d，

选项仅将分隔符设置为逗号）

尝试重新发明轮子似乎要容易得多。

使用阵列可以轻松完成

OLD=$IFS; IFS=$'\n'
ar1=( $(cat file1) )
ar2=( $(cat file2) )
IFS=$OLD
ind=${!ar1[@]}

for i in $ind; { echo "${ar1[$i]}, ${ar2[$i]}"; }

是否确实要为每条记录复制

帐户ID

？这在一组数据中似乎是唯一的？如果您不打算复制

帐户\u ID

请告诉我，我将取消删除我的答案。
