I understand that this command line
will create a tarball

but what does the -czvf mean?

And this unpacks it.

tar -xzvf backup.tar.gz

What does the x mean?

thanks.

hello
i did this command in php "tar czvf back.tar.gz /web/htdocs/www-eticalis-org/home/"
it's work as perfect but this is for linux only?
because i found other server folder is "D:\Hosting\4882069\html" maybe not work on server host windows? there is other solution?

this is php for linux:

<?

//Creating the file to compress:
exec("echo 'This is a test file to be compressed.' > testfile.txt");

echo 'Compressing...';

//Run the command and print out the result string
echo exec('tar czvf back.tar.gz /web/htdocs/www-eticalis-org/home/');

//Check out the compressed file:
echo '<a href="back.tar.gz" target="_blank">Get the file now</a>';

?>

version windows??? see :

<?

//Creating the file to compress:
exec("echo 'This is a test file to be compressed.' > testfile.txt");

echo 'Compressing...';

//Run the command and print out the result string
echo exec('tar czvf back.tar.gz D:\Hosting\4882069\html\');

//Check out the compressed file:
echo '<a href="back.tar.gz" target="_blank">Get the file now</a>';

?>
