Renaming Large Files

When I have a file for example with the wrong name I normally use the cp {filename} {new filename} comand so I will have the original as well as the correct named file. Just for backup purposes.

Problem: I have a file that is 24gb with a case sensitive filename. The file was named with upper case but the script is looking for lower case. What is the easiest and quickiest way to rename the file. I dont want to use cp as it will take to long and space is an issue.

Will the mv command copy the contents of the file to the new name or will it just rename the file?

mv will rename the file as long as you stay in the same directory.
Example for rename:
mv file.a file.b

Example for copy & delete:
mv file.a ..

Or, if you want to keep the file with the old name too, link it:
ln -s CASE.SENSITIVE case.sensitive
