When running a command on a file, is there any way to reference the file without typing the entire name?

For example:
tar xvf test.tar.gz ; rm test.tar.gz
Is there a faster way to reference the file name on the second execution?
I was thinking something like this (which is invalid):
tar xvf test.tar.gz ; rm $1
Anything possible?
I'm fully aware of wildcards.

You could assign the filename to a variable first:
f=test.tar.gz; tar xvf "$f"; rm "$f"
Or use the $_ special parameter, it contains the last word of the previous command, which is often (but of course not always) the filename you've been working with:
tar xvf test.tar.gz; rm "$_"
This works with multiple commands too, as long as the filename is always the last argument to the commands (e.g. echo foo; echo $_; echo $_ prints three times foo.)
As an aside, you may want to consider using tar ... && rm ..., i.e. with the && operator instead of a semicolon. That way, the rm will not run if the first command fails.
