Think I need to rename path in PuTTY?

[Caterix]

Hi all. I'll try to cut a long story short! My Kindle 4NT was working perfectly with custom screensavers. Then I realised I couldn't update to 4.1 because of the custom screensavers. I attemped to follow some instructions to reverse the procedure so I can get it to update. Nothing would work, and now I don't have any screensavers at all, just a white screen.
After much digging around, I think the problem is that when copying and pasting certain commands off the web to paste into putty, for some reason the "x" between 600x800 was being changed to a "?" . It took me a while to realise this, and now I think the reason I haven't got any wallpapers is because the kindle is looking for paths such as "mv mnt/base-mmc/opt/amazon/screen_saver/600×800", but it's all been changed to "mv mnt/base-mmc/opt/amazon/screen_saver/600?800" for example. I'm pretty sure this is the problem, but I have no idea how to change the relevant paths back to "600x800". Any help would be great, and in as simple terms as possible as i'm no expert at this by any means

Thanks!

Yup, we have seen that one before.

In *nix (Unix, Linux, any *nix) the "rename" function is called: "move" and the command is mv
(To move the data from one pathname/filename to another)

In *nix command line, like other command lines the ? character is a wildcard character.
So you have to quote any string that contains it.

Literally:
mv "mnt/base-mmc/opt/amazon/screen_saver/600?800" "mnt/base-mmc/opt/amazon/screen_saver/600x800"

When I write: "literally" I mean including the quote marks shown.

knc1, thanks for taking the time to reply and help me

You've just explained what I managed to do myself earlier, on a wing and a prayer, but I had no idea how what I'd done had fixed it. Having never worked with any form of nix, a "move" command to rename something is a very alien concept to me

Thanks again for the explanation!

Nope

Actually the opposite is true: "rename" is just a special case of "move a file to another position" - in this case the other "position" is simply its new name. And since the command to do that already exists (yep, "mv"), having an additional "ren" command would be superfluous and confusing.
