This will search for a keyword, number, or string of characters in multiple files, and return the ‘whole’ line to an output file. For example, let’s say you have a 100 text files located in a ‘Config’ folder. And, those files contain many different wireless configurations, but you only want to return lines with the SSID of skytrap. This will do that. This will return the lines that contain the keyword skytrap, and tell you which file the keyword was found in.
