Hi saweens,
As I understand you need to tar a set of files into a tar file on your Hard-Disk. If you have 2 files. lets say /home/saweens/.profile and /home/saweens/.sh_history then
1) Using Absolute Paths
$ tar -cvf tar_file_name.tar /home/saweens/.profile /home/saweens/.sh_history
2) Using Relative Paths
$ cd /home/saweens
$ tar_file_name.tar .profile .sh_history
The distinction between the Absolute and Relative Paths is that when you untar a file created with Absolute Paths, it will untar files to their absolute path no matter where you run the untar command from whereas you untar a file created with Relative Path, it will untar taking the present working directory as the base path.
Hope it helps.
