'mv' is a command that we're going to use to move files around or to rename them. 'mv' sort of has a split-personality because it serves these two functions at the same time. 'mv' command for renaming files Let's go back yet again to Tony's file, 'stuff' again. 'stuff' is not a good name for a file just as 'book' isn't a good name for a book. Just imagine: "The number one bestselling book this week is 'Book' by John Author. You should probably re-name this file to something meaningful. I would suggest doing something like this: Code: mv stuff tonys_jokes You may have noticed the underscore '_' in the title. It's there because Linux doesn't really like spaces in the file names. You can do it and Linux will accept it but it will put a \\ between the different words. Spaces are sort of 'faux pas' in Linux but not 'verboten'. It would be to your advantage to use '_' between words though. Moving files with the 'mv' command Now you can use the 'mv' command to move Tony's jokes into the directory you made to keep his files. Code: mv tonys_jokes tonyd/ If you do cd tonyd and then ls to* you will see his file there along with 'toms_jokes' and 'tomato_soup_recipe'. (if you have another friend named Tom and you like to cook) You can also move entire directories with this command. You do not have to use the '-r' option as you did with 'cp'. You would just substitute the file name for a directory name Code: mv tonyd/ my_friends/ would move the directory 'tonyd' to the directory 'my_friends'.
