查找包含一個字元串但不包含另一個字元串的文件

我在一個有很多文件的.txt文件夾中，我想找到所有包含stringA但不包含的文件stringB（它們不一定在同一行）。有誰知道如何做到這一點？

只要您的文件名不包含空格、製表符、換行符或萬用字元，並且如果您grep支持該-L選項，您可以按以下方式進行操作：

$ cat file1
stringA
stringC
$ cat file2
stringA
stringB
$ grep -L stringB $(grep -l stringA file?)
file1

在grep子shell 中執行$()，將列印所有包含stringA. 此文件列表是主grep命令的輸入，其中列出了所有不包含stringB.

從man grep

  -v, --invert-match
          Invert the sense of matching, to select non-matching lines.  (-v is specified by POSIX.)

  -L, --files-without-match
          Suppress normal output; instead print the name of each input file from which no output would normally have been printed.  The scanning will stop on the first match.

  -l, --files-with-matches
          Suppress normal output; instead print the name of each input file from which output would normally have been printed.  The scanning will stop on the first match.  (-l is specified by POSIX.)
