使用awk函数的时候出现的问题报错:awk: 1: unexpected character '.'

这是我的代码，不知道为什么一直出现awk: 1: unexpected character '.' ，我寻思我的目标文档里面也没有.啊

#!/bin/bash
awk -F '{print $1}' Part.csv>1.txt
PARTNUMBER=$(cat ./1.txt)
for line in $PARTNUMBER
do 
awk -F "," '{if($1~/^$line/) print $1,$2,$3}' Part.csv>10.txt
done
sed 's/-//' 1.txt>2.txt
PARTNUMBER2=$(cat ./2.txt)
for line2 in $PARTNUMBER2
do 
awk -F "," '{if($1~/^$line2/) print $1,$2}' MFPart.csv>10.txt
done
cat 10.txt

awk 1 unexpected character '.' suddenly appeared
大致意思就是说：1个意外字符’.’ 突然出现
改成这样试试：#!/bin/awk -f
希望对题主有所帮助，望采纳！！
