The Linux command shell provides a very powerful interface for doing various system tasks. This video explains with an example, how to use a bit of programming techniques to batch rename files with similar naming conventions. The narrator first displays the names of the files in the current directory using the l command and then, using a for loop and a move command in the shell window, interchanges the prefixes and suffixes of two similarly named files. An echo keyword is also used, so that the steps being executed are clearly visible. The narrator also provides helpful insights so that the workings of the commands are clearly understandable.
