Getting started with Drupal install on the command line:
In a Web browser (firefox), go to http://drupal.org/ and copy the latest drupal version folder location which you want to install. Just right click on download Link and copy to clipboard.
Go to www or public_html or your installation folder usign ssh.
Use Wget command to download drupal from site.
$ wget <paste link here>
$tar -xzf drupal-6.19.tar.gz
You can create shortcut name for this drupal folder. As some people would like to rename this directory to some simple name.
You can create a link such as:-
$ln -s drupal-6.9 drupal
so that you can keep multiple versions in your account at once without getting confused as to which is which. "ln -s" stands for "link symbolically"
It is now safe to delete the file you downloaded, like so:
"rm" stands for "remove." and helpful command for deleting directories. -rf can be used for force delete of directories.
Go to your new URL in a Web browser and follow the directions there.Installation instructions will come up there and you need to follow those.
You can fastely download modules from drupal site to your drupal directory / theme or module directory and enable from drupal GUI. You can also create a script for auto update and installations of modules and themes from drupal site. But need to make sure about backups :-)
