This might be a dumb question and is probably more of a general question for using the command line, but how can I create a command setting where drush is set in the current terminal session. I already have the correct path set where I don't have to type the full path to drush every time, but I'd like to be able to open the terminal up with drush set in the session until I exit the terminal.
For instance instead of opening up terminal and having to type drush everytime:
$ drush dl ctools
$ drush en ctools
$ drush .... (everything else that you want to do)
I can open up the terminal where drush is already set, something like this where drush becomes the user and I don't have to type it:
drush$ dl ctools, pathauto, ... drush$ en ctools
