從字符分隔文件中讀取並分配給變量| ksh Unix shell

我正在使用ksh。從字符分隔文件中讀取並分配給變量| ksh Unix shell

我需要將文件中的數據讀入變量，然後進一步使用它們發送電子郵件。

文件可以由任何較少使用的字符（如| ^等）或一組字符分隔。
需要檢索從郵件，郵件到，抄送，密送，主題，身體從文件。
我從表中假脫機到文件，因此分隔符可以是任何字符，但較少用於一般的英語，因爲字符，如& *等可能存在於身體，並可能返回錯誤的值。

文件：（CC和BCC沒有在文件中提供即它們是空白）使用

代碼：

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

它沒有設置變量。

及以下使用代碼時：它示出了不期望的輸出：

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

輸出：（地獄很多空行）

你不只是需要解析第一線？ – SMA 2015-01-21 08:28:03

它不只是一條線。相反，它只是一個單一的條目。問題是，最後一個條目是電子郵件的BODY，它本身確實有很多行。 – Sachin 2015-01-21 08:30:10

也許可以使用'cut'來分配每個變量？ 'cut -f1 -d'|''使用f1到f6？ – Jmoreland91 2015-01-21 16:46:24

在KSH，最後一個命令在一個管道中在當前shell中執行。

我會處理第一行，然後將所有其他行添加到body變量。

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"

有時我喜歡的地方使用sed的head/tail

唯一的問題是僅在BODY中，這裏又來了。所有其他字段都顯示正常，但是對於正文，它顯示了這個錯誤：generate_error_file.ksh [174]：body + = $ \ n：not found .. PS：我是shell的新手，因此沒有那麼多它的知識。 – Sachin 2015-01-21 12:18:51

另外，我發現了一些替代解決方案，將BODY在另一個文件中單獨打印並使用。無論如何，我將直接在'mailx'命令中使用該文件作爲主體。 – Sachin 2015-01-21 12:21:08

你可能有一個較老的ksh。我更新了文本附加到body變量的方式 – 2015-01-21 12:24:00

我用cut命令，它似乎運作良好將其分配給變量。雖然，我不確定您的文件是否有多個條目。

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
