Explanation

find . -name *conf* In current directory, recursively find all files with 'conf' in the filename.

-exec grep -Hni 'matching_text' {} \; When a file is found matching the find above, execute the grep command to find all lines within the file containing 'matching_text'.

Here are what each of the grep switches do:

grep -i ignore case.

grep -H print the filename

grep -n print the line number

> matching_text.conf.list Direct the grep output to a text file named 'matching_text.conf.list'
