So basically I have three files, two with permission 744 and one with 601 and I want to list the names of the files that have permission 744 and in addition, it also have to have string "def" anywhere in the lines of the file.

All I got is how to print out if they have permission 744:

```
find * -perm 744

```

How do I get it so it can check for string "def"?

Any help is appreciated.
