There are alternatives to the methods described above. If the text is found in the file, its name will be added to the output, thanks to the -l option. The -exec option calls the grep tool for each of the matching files to check their contents. type f -exec grep -l "text to find" \ XFCE4 terminal is my personal preference.įind.
