And if you want to know how it happens step by step, here it is: first you have a gzip-compressed tar-archive called gsmile-0.1.1.linux-i686.tar.gz
. Then you gunzip-uncompress it:
and you get the tar file out of it, called gsmile-0.1.1.linux-i686.tar
Then you untar it with
tar -xf gsmile-0.1.1.linux-i686.tar
and get out whatever is in the tar archive. The command tar -xzf
simply includes the "gunzip" part (the -z option; it would be -j for bzip2 archives), making these two steps in one command.
