How to find filename in file content with bash script?

Question

I wrote this command in my shell but it's not doing what I wanted and I can't figure out what I did wrong. I want to get files from current directories which include their names in their content.

find -type f -exec grep -il {} +

I understand find -type f gives me standard files from the directory and -exec executes following grep command with pattern - which is filename - on given file ('+'). Am I right? Because it seems like I don't understand something since it's not finding my file specially created for this purpose.

Answer 1

on given file ('+')

+ executes the command on all found files. The {} is replaced by the list of files in current directory.

Debug with -exec echo grep -il {} +.

You want:

-exec grep -Fil {} {} ';'

To search the filename {} as a pattern in the file named {}. The ';' terminates the command.

I also added -F to interpret pattern literally.

Answer 2

File in current directory test.txt

Content of file includes "test"

find . -name 'test.txt' -exec grep -i 'test' {} \;
