tar instructions

Before electronically submitting your project code, use tar and gzip to create a compressed "tape" archive file of your project directory:

First make sure that your code is sitting in its own subdirectory, e.g., in my case, my code is in my .../asg01 directory:

	[andrewd@pupil] ~/teaching/dpa401/src/examples/asg01 > ls
	Makefile        asg01.h         asg01.cpp
	[andrewd@pupil] ~/teaching/dpa401/src/examples/asg01 >

Do a make clean to clean up all the *.o and executable files (to reduce space):

	[andrewd@pupil] ~/teaching/dpa401/src/examples/asg01 > make clean
	rm -f asg01.o  core

Change directories to one above the current project directory, e.g.:

	[andrewd@pupil] ~/teaching/dpa401/src/examples/asg01 > cd ..
	[andrewd@pupil] ~/teaching/dpa401/src/examples >

Create the tar file. The command syntax is:
```
	tar cvf <file.tar> <directory>
	
```
where <file.tar> is the tar file being created, and <directory> is the directory which will get archived (stuffed) into the single tar file. You'll see a list of a <directory/file> additions being assembled into the tar file. You will then have the file <file.tar>.
```
	[andrewd@pupil] ~/teaching/dpa401/src/examples > tar cvf asg01.tar asg01/
	asg01/asg01.cpp
	asg01/asg01.h
	asg01/Makefile
	...
	
```
Compress the tar file using gzip:
```
	[andrewd@pupil] ~/teaching/dpa401/src/examples > gzip asg01.tar
	
```
You'll now see the file <file.tar.gz>. This is the file you want to submit electronically.
