以下に2つのファイルがあります。

$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'"

file2を読んでいて、grepを使用して、file1（大きなファイル）の行を見つけています。私はそれを以下のようにやっています：

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

しかし、私は以下のように結果を下回っています：

grep: can't open less
grep: can't open times

grep: can't open the

あなたが探しているものを引用してみてください：

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

パターンを引用する必要があります。

しかし、あなたが実際にすべきことは、スイッチを介しfile2てgrepするために直接の文字列を提供することだと思います-f：

grep -Ff file2 file1

次に、 の固定文字列がfile2から grep されfile1ます。

の行が正規表現の場合は、スイッチfile2を省略してください。-F

grepの最初のパラメーターに二重引用符を追加します

grep "$line" file1

また

grep "${line}" file1

引用符を使用して、 cat の無用な使用を削除します。

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