help renaming files.

[mactruck]

In our system we have a script that renames files that it does not know what to do with. When it renames the file it adds a "?" to the end of the file name. Now I cannot move these files to the FTP because of the question mark in the file name. I know how to rename each file individually with the move command. Is there a way I can do this on a bigger level? I would like to create an alias for this so I can do it with ease. Our system does not have the "rename" command. I see that this should be able to do what I want but it is not installed. I dont have the rights to install.

here is what the file names look like:

note: I have tried just adding .txt to the end and it sill wont let me upload to the ftp. I need to remove the "?"

simply

for f in *.\? ; do mv "$f" "${f%.?*}"; done

maybe, simply protecting filename's question mark(s) can help ftp to transfer those files?
