Recently，I Try to use the Snow Leopard ,But it lacks a feature.

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.

bash执行时，不管是何种方式，都会读取此文件。

（3）~/.profile
若bash是以login方式执行时，读取~/.bash_profile，若它不存在，则读取~/.bash_login，若前两者不存在，读取~/.profile。
