Tar and untar
To compress a file/folder into a .tar.gz archive:
tar cvfz archive.tar.gz folderTo decompress a folder/folder:
tar xvfz archive.tar.gzInstall a binary
If you’re working on a local machine with administrator permissions, you may want to add downloaded-binary to your PATH, so that you can access it directly from any project folder. You could do this by extracting it to a directory that is already on your PATH. (For example, /usr/local/bin is a common choice for Mac and Linux.).
# navigate to download location of .tar.gz
sudo mv downloaded-binary.tar.gz /usr/local/bin/downloaded-binary.tar.gz
sudo tar zxf downloaded-binary.tar.gzSee further details on how to install a binary.
