Creating a tar file:

tar -cvwf file.tar myfile.txt

In the above example, the system would create a tar named file.tar in the directory you currently are in. Wildcards could also be used in this command, for example: tar -cvwf file.tar *.txt would archive all txt files in the current directory.

tar -cvwf home.tar home/

tar -cvf lampp.tar /opt/lampp/

In the above example command the system would create a tar file named home.tar containing the home directory and place that file in the current directory.

.tgz and tar.gz files are pretty much the same. You extract them like this:

Code:

tar xvzf file.tar.gz
tar xvzf file.tgz
