语法错误：未终止的带引号的字符串。找不到错误

我正在编写一个脚本来将较大的文件解析为可用数据。我将附上下面的脚本。该脚本没有按照我想要的方式运行，我认为这可能是我使用的 if/then 语句，但是当我将其取消时，它揭示了真正的问题。这就是我现在遇到的错误，这使得真正的问题看起来像是某种引号。

FirstName,LastName,Company,Address,City,County,State,ZIP,Phone,Fax,Email,Web
FinalProject.sh: 36: FinalProject.sh: Syntax error: Unterminated quoted string

虽然我从技术上理解语法错误的含义，但我找不到问题出在哪里，并且我已经尝试修复它大约半个小时。帮助将不胜感激！

#!/bin/bash

OLDIFS=${IFS}
IFS=$'\n'

head -1 50000_a.csv | sed 's/"//g'
for LINE in 'grep WV 50000_a.csv | sed 's/"//g' | awk -F, '{print $(NF-11)"," \ 
    $(NF-10)"," \ 
    $(NF-9)"," \

一般来说，您使用单引号'...'来包裹“命令执行”，它应该用反引号`...`或（更好）包裹起来$(...)。

for LINE in 'grep这使得以：开头并以以下结尾的 行}''失败。
进行尽可能少的更改，代码变为：

#!/bin/bash

OLDIFS=${IFS}
IFS=$'\n'

head -1 50000_a.csv | sed 's/"//g'
for LINE in `grep WV 50000_a.csv | sed 's/"//g' | awk -F, '{print $(NF-11) "," \
    $(NF-10)"," \
    $(NF-9)"," \
    $(NF-8)"," \
    $(NF-7)"," \
    $(NF-6)"," \
    $(NF-5)"," \
    $(NF-4)"," \
    $(NF-3)"," \
    $(NF-2)"," \
    $(NF-1)"," \
    $NF \
}'`
do
    FNAME=`echo ${LINE} | awk -F, '{print $1}'`
    LNAME=`echo ${LINE} | awk -F, '{print $2}'`
    COMPANY=`echo ${LINE} | awk -F, '{print $3}'`
    ADDRESS=`echo ${LINE} | awk -F, '{print $4}'`
    CITY=`echo ${LINE} | awk -F, '{print $5}'`
    COUNTY=`echo ${LINE} | awk -F, '{print $6}'`
    STATE=`echo ${LINE} | awk -F, '{print $7}'`
    ZIP=`echo ${LINE} | awk -F, '{print $8}'`
    PHONE=`echo ${LINE} | awk -F, '{print $9}'`
    FAX=`echo ${LINE} | awk -F, '{print $10}'`
    EMAIL=`echo ${LINE} | awk -F, '{print $11}'`
    WEB=`echo ${LINE} | awk -F, '{print $12}'`
done

然而，尝试这样做是错误的使用 for 循环处理文件， 你应该用于read获取输出grep:

#!/bin/bash

OLDIFS=${IFS}
IFS=$'\n'

head -1 50000_a.csv | sed 's/"//g'
while IFS=$'\n' read -r LINE
do
    FNAME="$(echo ${LINE} | awk -F, '{print $1}')"
    LNAME="$(echo ${LINE} | awk -F, '{print $2}')"
    COMPANY="$(echo ${LINE} | awk -F, '{print $3}')"
    ADDRESS="$(echo ${LINE} | awk -F, '{print $4}')"
    CITY="$(echo ${LINE} | awk -F, '{print $5}')"
    COUNTY="$(echo ${LINE} | awk -F, '{print $6}')"
    STATE="$(echo ${LINE} | awk -F, '{print $7}')"
    ZIP="$(echo ${LINE} | awk -F, '{print $8}')"
    PHONE="$(echo ${LINE} | awk -F, '{print $9}')"
    FAX="$(echo ${LINE} | awk -F, '{print $10}')"
    EMAIL="$(echo ${LINE} | awk -F, '{print $11}')"
    WEB="$(echo ${LINE} | awk -F, '{print $12}')"
done < <(
    grep WV 50000_a.csv | sed 's/"//g' | awk -F, '{print $(NF-11) "," \
    $(NF-10)"," \
    $(NF-9)"," \
    $(NF-8)"," \
    $(NF-7)"," \
    $(NF-6)"," \
    $(NF-5)"," \
    $(NF-4)"," \
    $(NF-3)"," \
    $(NF-2)"," \
    $(NF-1)"," \
    $NF \
    }'
)
