Changing a file extension to a new one for all files in a directory.
An entirely shell-based solution (should work on any bourne-style shell), more portable on relying on the rename command, the exact nature of which varies from distro to distro.
This command can be used to rename all the files with extension .xls( in this case) to .ods files. It can be used for other files with certain extension.
The 'rename' command with the first argument as "'s/\.//'" and the second argument as "" will remove the specified extension from the filenames.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
