Hi Kaichao, wc is very simple: it just counts the number of characters, words and lines in a plain-text file. In general, if you are unsure about any command, I recommend using man, e.g. man wc Finally, beware of using ChatGPT for anything; it can "hallucinate", i.e. report nonsense, just because certain words are statistically associated. If you wish to use the web, I strongly recommend using sites such as Stack Overflow. (Beware of sites that offer to help you. There are several of those too.) Cheers MichaelW
