I installed Drush with apt-get install drush. which drush says the file has been installed on /usr/bin/drush.
I would like to manually update Drush as well as adding files like an example.alias.php file to that folder. However, /user/bin/drush isn't actually a folder but the PHP file itself.
How can I find the Drush folder?
It is installed here:
/usr/share/drush
