Linux：计算名称和内容中包含单词的文件

Question

I want to count files in directory that in its name and content contains a given word.

find ./test -maxdepth 1 -type f -iname "*main*" | wc -l

Given snippet counts files that contains "main" in name. How to change it to check if it contains "main" in its content as well?

Answer 1

Loop over your files and use grep -q which suppresses grep output:

for file in `find ./test -maxdepth 1 -type f -iname "*main*"`; do
    if grep -q main $file; then
        wc -l $file
    fi
done

Output

5 ./test/foo_main

Answer 2

find ./test -maxdepth 1 -type f -iname "*main*" -exec grep -q main {} \\; -exec printf '\\n' \\; | wc -l

-exec printf '\\n' \\; instead of -print protects against filenames with newline characters.
