Some of us old terminal jockeys were annoyed that bash completion was enabled on new Ubuntu installs. Here’s the description for the package:
bash completion extends bash’s standard completion behavior to achieve
complex command lines with just a few keystrokes. This project was
conceived to produce programmable completion routines for the most
common Linux/UNIX commands, reducing the amount of typing sysadmins
and programmers need to do on a daily basis.
The idea is pretty interesting: provide more intelligent tab completions to commands. For example, if you type ‘mysqladmin flush-p<tab>’ it will complete the term ‘flush-privileges’. Very neat.
In practice, those who are quite familiar with tab completion for files and directories may find themselves banging their heads on the tables. One of my fellow programmers was annoyed trying to get filename completion after a perl -d.
Uninstalling should be as simple as this:
sudo apt-get remove bash-completion
Unfortunately, that still leaves files behind, and hence – not really uninstalled. In fact, if you do a dpkg -l bash-completion, you’ll see it’s in status ‘rc': removal desired, config files remain. Easily fixed:
sudo dpkg --purge bash-completion
Log out and log in, and voila – all gone!
If you’re sharing the system with other people who do like tab completion, you’re probably better just adding the following to your .bashrc:
With no arguments, this will remove all bash completion statements. You could also use that to fine tune what bash completion. This would remove bash completion for emacs, ack, and perl:
complete -r emacs ack ack-grep perl
To verify that it’s removed, try:
This prints all completions currently active.
