Rename files by regexp in command line

view full story

http://askubuntu.com – I do a mistake when trying to move files from one location to another. Now all files are moved, but there is a * concatenated at the end of all names. How do I remove all *s from end of file names in command line? Note: I'm working with an embedded system, there is not any Internet connection. Please provide solutions with no need to install new stuff. Thanks in advance (HowTos)
