Using Tar

Suppose that you have a directory called "class", and in the "class" directory there is a subdirectory called "hw9". In the "hw9" directory are the three files: freq1.v freq2.v clock.v, as shown below:

                                                        class
                            |
                                                ____ hw9 ____
                                             /        |             \
                    freq1.v     freq2.v     clock.v

Now, if you want want to place EVERYTHING in the directory of hw9 into a tar file, you can do the following: While in the "class" directory, type the command:

tar -cvf hw9.tar hw9

"-cvf" are flags for Create, Verbose, File, meaning that you are going to Create the tar file called "hw9.tar". Verbose means that it is going to list the files as tar puts them into the tar file.
The general format of the tar command is: tar [-flags] target_filename files_or_directory.
As another example, if you wanted to submit just the files "freq1.v", and "freq2.v" then you could do:

tar -cvf freq.tar freq1.v freq2.v

This would have to be done while in the hw9 directory.
It is generally preferable to tar up entire directories as in the first example, since you are less likely to leave something out. With this in mind, please make sure that files that you do NOT want to submit are not in the directory.
To extract files from a tar file, you would do: tar -xvf hw9.tar
By convention, tar files should always be given a .tar suffix.
