Mac Bash Completion is package providing command-line completion for a number of Mac-specific tools in the Bash shell. The commands are described in detail below.

• Mac Bash Completion 1.0

• bash-completion by Ian Macdonald. This is available at the previous link, or can be easily installed through MacPorts or Fink.
• Bonjour Lister for SSH host completion (binary included)

Copy the command completion files to a common location:

% mkdir -p ~/Library/init/bash/completion
% cp completion/* ~/Library/init/bash/completion/

Copy Bonjour Lister to somewhere in your path:

% sudo cp Bonjour\ Lister\ 1.0/blister /usr/bin/

Then source them from your .bashrc or .bash_profile. This example first loads the bash-completion package installed through MacPorts.

# Set up completions
if [ -f /opt/local/etc/bash_completion ]; then
    source /opt/local/etc/bash_completion
 
    for cmd in ~/Library/init/bash/completion/* ; do
        source $cmd
    done
fi

Completion for defaults will fill in all command options, domains, and keys. Additionally, defaults write will insert the current value and type. Here's a text example until I put up a video:

% defaults w <tab>
% defaults write com.apple.te <tab>
com.apple.Terminal  com.apple.TextEdit
% defaults write com.apple.Terminal nsfi <tab>
NSFixedPitchFont      NSFixedPitchFontSize
% defaults write com.apple.Terminal NSFixedPitchFontSize <tab><tab>
% defaults write com.apple.Terminal NSFixedPitchFontSize -integer 9

SSH completion is a small enhancement on the existing bash-completion. The bash-completion package is used to complete some arguments and known hosts. The Mac Bash Completion package adds completion of local Bonjour hosts, and suppresses unavailable *.local hosts. Bonjour Lister is used to find local hosts.

The xcodebuild command builds Xcode proejcts from the command line. All options and commands are completed, including the project's targets and configurations.

% ls
Bonjour Lister.xcodeproj/       _darcs/                         main.c
LICENSE.txt                     build/
% xcodebuild <tab>
-activeconfiguration  -help                 -version              installsrc
-activetarget         -list                 build                 
-alltargets           -project              clean                 
-configuration        -target               install
% xcodebuild -proj <tab><tab>
% xcodebuild -project Bonjour\ Lister.xcodeproj -conf <tab><tab>
Debug    Release
% xcodebuild -project Bonjour\ Lister.xcodeproj -configuration Release -t <tab><tab>
% xcodebuild -project Bonjour\ Lister.xcodeproj -configuration Release -target Bonjour\ Lister
