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.

          You can use !$ if you move the second command to a new line.



          tar xvf test.tar.gz
          
rm !$

En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1.
