读取行时sed替换变量 [英] sed replace variables while read lines

问题描述

我正在处理Shell脚本，我需要将一些字符串从文件的不同行更改为while读取语句.结构必须像这样，因为String_Search和String_result将在每一行上计算.

I'm working on a shell script and i need to change some strings from different lines of a file into a while read statement. The structure need to be like this, because the String_Search and String_result will be calculated on each line.

while read line 
do  
   varA="String_Search"   
   resA="String_Result"
   line=`echo $line | sed -e "s/$varA/$resA"`
   echo $line >> outputFile.txt
done < "inputFile.txt"

该脚本无法正常工作，并且向我显示此错误消息:

The script doesn't works and its showing to me this error message:

sed: -e expression #1, char 31: unterminated `s' command

任何人都可以帮助我吗?

您需要以斜杠/

line=`echo $line | sed -e "s/$varA/$resA/"`
