massrename is a general-purpose utility for
batch-renaming file extensions, as well as strings within the base filename (for example, "SomeblehFile.mp3" to "SomeblahFile.mp3").
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
Minor bugfixes. The README file has been revised. An optional argument "--ignore-case" has been added, allowing massrename to ignore the case of filenames to be renamed at runtime. Debian and Red Hat package formats have been added.
