Debian-like bash_completion! I missed you! So I Seached with Google!

To install it just do:

sudo port install bash-completion
echo "source /opt/local/etc/bash_completion" >> ~/.bash_profile
chmod +x ~/.bash_profile

Tip: You must have MacPorts installed to run the first command. MacPorts Form http://www.macports.org .

If you don’t know yet what is bash_completion, it is  a feature for shells to autocomplete commands. Example: You are on a git repository. You type git fe and press TAB, bash_completion will fill “fetch” for you. If you have branches, they are autocompleted too. GNU Tar only shows files compatible with the filters you selected. So if you tar xvzf my-softw TAB, it will complete only filenames that are on tar.gz or tgz format and that starts with the string you already typed.

It is heaven again.

1. Install bash-completion

First of all we need the install the according package:

apt-get install bash-completion

2. Add it to the bash profile

Either edit the ~/.bash_profile file to enable it only for a given user or edit /etc/profile to add it system-wide. Add the following code:

if [ -f /etc/bash_completion ]; then
 . /etc/bash_completion
fi

3. Try it
In order for it to work you have to log out and relogin and then you can make use of bash completion the usual way. E.g. issue:

apt-g

and then press the TAB key once and the command will be completed to apt-get. Or issue this:

apt

and then press TAB key twice. You can also try with

apt-get install apa

and then press TAB key once to complete as far as possible and a second time to list all options.
