To make sure files aren't removed accidentally when running the Linux find command, use the -ok command. It will ask for permission before removing any files.

Using the -ok parameter, the find command will take the action specific (the “head -1” command in the example below) only if you confirm by typing “y” or “Y” at the prompt.

The first option in the Terminal is the classic "find" command that is common to many Unix systems, which will recursively walk a specified folder hierarchy and search items for a given name pattern.
