Invoking the rm utility once for each of half a million times is going to be a LOT slower than invoking the rm utility fifty thousand times with each invocation removing 100 files.
Although not in the standards, many implementations of the rm utility have a "verbose" option such that adding a -v option to each invocation of rm will print the name of each operand removed after it is removed. If you would tell us what operating system and shell you're using, we might be able to make an easy suggestion that would work in your environment.
How did you get the list of 500,000 files to be removed? If you create the list using find, you could have find remove the files instead of just list files to be removed. If the names of the files are in another file, xargs could be used to create groups of files to be processed by rm.
You have given us very little information about your environment. The less information we have, the fewer options we can suggest to solve your problem. Please help us help you.
