# Iterm2 配色方案

### 先要修改 ~/.bash_profile. 添加代码如下:

	# enables colorin the terminal bash shell export
	export CLICOLOR=1

	# sets up thecolor scheme for list export
	export LSCOLORS=gxfxcxdxbxegedabagacad

	# sets up theprompt color (currently a green similar to linux terminal)
	export PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;36m\]\w\[\033[00m\]\$ '

	# enables colorfor iTerm
	export TERM=xterm-256color

### 选择喜欢的配色方案。

	在Preferences->Profiles->Colors的load presets可以选择某个配色方案。也可以自己下载。在网站http://iterm2colorschemes.com/，几乎可以找到所有可用的配色方案。

### 小写敏感 - 对于目录中经常有大写字母的情况，取消大小写敏感。代码如下：

    echo "set completion-ignore-case On" >> ~/.inputrc
