"AM" 2.3.1 is out with a more efficient bash completion support!
I have removed the old "-d"|"db"|"database"|"terminal" option which instead had characterized the previous 2.3.0 and 2.2.5 releases in favour of two newer and more efficient options to enable/disable bash completion in "AM":
--enable-completion and --disable-completion
These options will create/remove a /etc/bash_completion.d/am-completion.sh script that can read the list of all the scripts available in the "AM" repository and for your architecture.
After the update, I suggest to use the am -c command to remove the old and now obsolete" appdb "directory.
To enable bash completion
[sudo] am --enable-completion
the path to this script will also be listed in the /opt/am/remove script needed to uninstall" AM ".
To disable bash completion
[sudo] am --disable-completion
To create your own bash completion script, I suggest this guide.
