TIL: tar has --transform

I often have more than one version of a particular utility installed, and switch between them as needed. Out of habit, I will often append the version to the executable. For example, terraform-0.8.0-RC1 instead of terraform.

TIL, tar has --transform to do this for you, and to save you from overwriting an existing symlink or other file. In practice, it looks like:

ᐅ tar -xf foobar.tar.gz -zvp                  \
       ...                                    \
       --transform=s,my_util,my_util-0.1.2,   \
       my_util
