What Others Think

I had taken note of this command, this was useful to convert the file names of my camera I do not know why that makes the extension of the file type in uppercase. Yesterday I re showing it to a person who boasted Windows 7. I asked him if he were able to rename to less than 1 minute all the files in a folder. Of course opened explorer and did not even had time to change the name of the first file (by hand) that this command had already finished. So I will sign a +1 to Karakh

Curiously, this does not work for me at all (on SLES 11 SP1, using bash 3.2.51, rename version string: "rename (util-linux-ng 2.16)"). The man page shows a differing syntax, too. Which version of rename are you using?

The `-f` flag is required on MacOS (to replace the existing files).
