从字符分隔文件中读取并分配给变量| ksh Unix shell

我正在使用ksh。从字符分隔文件中读取并分配给变量| ksh Unix shell

我需要将文件中的数据读入变量，然后进一步使用它们发送电子邮件。

文件可以由任何较少使用的字符（如| ^等）或一组字符分隔。
需要检索从邮件，邮件到，抄送，密送，主题，身体从文件。
我从表中假脱机到文件，因此分隔符可以是任何字符，但较少用于一般的英语，因为字符，如& *等可能存在于身体，并可能返回错误的值。

文件：（CC和BCC没有在文件中提供即它们是空白）使用

代码：

while IFS='|' read -r a1 a2 a3 a4 a5 a6 
do 
flag1=`echo $a1` 
flag2=`echo $a2` 
flag3=`echo $a3` 
flag4=`echo $a4` 
flag5=`echo $a5` 
flag6=`echo $a6` 
done < $RUNTIME/EMAIL_$System`date +%y%m%d`.csv

它没有设置变量。

及以下使用代码时：它示出了不期望的输出：

while IFS='|' read -r a1 a2 a3 a4 a5 a6 
do 
echo $a1 
echo $a2 
echo $a3 
echo $a4 
echo $a5 
echo $a6 
done < $RUNTIME/EMAIL_$System`date +%y%m%d`.csv

输出：（地狱很多空行）

你不只是需要解析第一线？ – SMA 2015-01-21 08:28:03

它不只是一条线。相反，它只是一个单一的条目。问题是，最后一个条目是电子邮件的BODY，它本身确实有很多行。 – Sachin 2015-01-21 08:30:10

也许可以使用'cut'来分配每个变量？ 'cut -f1 -d'|''使用f1到f6？ – Jmoreland91 2015-01-21 16:46:24

在KSH，最后一个命令在一个管道中在当前shell中执行。

我会处理第一行，然后将所有其他行添加到body变量。

file="$RUNTIME/EMAIL_$System$(date +%y%m%d).csv" 
sed 1q "$file" | IFS="|" read -r from to cc bcc subj body 
body="$body 
$(sed 1d "$file")" 

printf "%s: %s\n" from "$from" to "$to" cc "$cc" bcc "$bcc" subj "$subj" body "$body"

有时我喜欢的地方使用sed的head/tail

唯一的问题是仅在BODY中，这里又来了。所有其他字段都显示正常，但是对于正文，它显示了这个错误：generate_error_file.ksh [174]：body + = $ \ n：not found .. PS：我是shell的新手，因此没有那么多它的知识。 – Sachin 2015-01-21 12:18:51

另外，我发现了一些替代解决方案，将BODY在另一个文件中单独打印并使用。无论如何，我将直接在'mailx'命令中使用该文件作为主体。 – Sachin 2015-01-21 12:21:08

你可能有一个较老的ksh。我更新了文本附加到body变量的方式 – 2015-01-21 12:24:00

我用cut命令，它似乎运作良好将其分配给变量。虽然，我不确定您的文件是否有多个条目。

Testing.sh

#!/usr/bin/ksh 

a1=$(cat test.txt | cut -f1 -d '|' -s) 
a2=$(cat test.txt | cut -f2 -d '|' -s) 
a3=$(cat test.txt | cut -f3 -d '|' -s) 
a4=$(cat test.txt | cut -f4 -d '|' -s) 
a5=$(cat test.txt | cut -f5 -d '|' -s) 
a6=$(cat test.txt | cut -f6 -d '|') 

echo $a1 
echo $a2 
echo $a3 
echo $a4 
echo $a5 
echo $a6
