Question

我有以下两个文件：

$cat file1
"2020051576BPI";"TS.1.BPI.20121129120000.005.txt";"Error";"'OF_USM_DBTI0000029'/'CO_SERVICE_SVCID11066'/'CO_FA_SC_600224'/. appears less times in the Input File (0), but should appear at least 1 times";""
"2019707951BPI";"TS.1.BPI.20121129120000.014.txt";"Error";"'OF_USM_DBTI0000029'/'CO_SERVICE_SVCID11066'/'CO_FA_SC_600224'/. appears less times in the Input File (0), but should appear at least 1 times";""
"Failed to parse string. Error msg: Failed to parse 'Fatal Error at file (buffer) "", line 366, column 17   Message: Expected whitespace'"

$cat file2
"'OF_USM_DBTI0000029'/'CO_SERVICE_SVCID11066'/'CO_FA_SC_600224'/. appears less times in the Input File (0), but should appear at least 1 times"
"Failed to parse string. Error msg: Failed to parse 'Fatal Error at file (buffer) "", line 366, column 17   Message: Expected whitespace'"

我正在读取file2并使用grep我在file1（大文件）中找到行。我这样做如下：

$cat file2|while read line
do
grep $line file1
done

但我的结果如下：

grep: can't open appears
grep: can't open less
grep: can't open times
grep: can't open in
grep: can't open the
grep: can't open Input
grep: can't open File

grep: can't open but
grep: can't open should
grep: can't open appear
grep: can't open at
grep: can't open least
grep: can't open 1
grep: can't open times"

Answer 1

尝试引用您要找的内容：

while read line
do
  grep -F "$line" file1
done < file2

Answer 2

你需要引用模式。

但是，我怀疑你实际应该做的是通过file2开关直接提供-f字符串grep：

grep -Ff file2 file1

然后file2中的任何固定字符串都会被file1格式化。

注意，如果file2的行是正则表达式，则应省略-F开关。

Answer 3

在grep

的第一个参数中添加双引号

grep "$line" file1

OR

grep "${line}" file1

Answer 4

使用引号并删除useless use of cat：

while read line
do
  grep -F "$line" file1
done < file2

使用grep的结果不同
