Please do not mistake this question with "how to untar a tar file into an existing directory". For this question there are already answers such as this one
What I am trying to do is to untar an tar.gz file but put the contents into a directory
The linked answer for example when you do it creates a folder (with the name of the tar file) and puts the contents inside the folder
What I want is to not create the folder but put the contents inside an already existing directory.
How can this be done?
