调整 Terminal.app 的配色

刚买来 MacBook Air 的时候,会发现它的终端简直挫爆了,白底黑字还没有颜色。然后许多人就会诉诸 iTerm2.app 这样的第三方应用。事实上只要简单配置一下,Terminal.app 也是不错的。

为了兼容大部分的 Linux 发行版使用习惯,在 ~/.bash_profile 中加入以下内容:

1
2
3

# Only for Mac OS X, where .bashrc is otherwise ignored
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi

这几行代码的作用是自动加载 ~/.bashrc 和 ~./bash_aliases 中的配置。其次,创建 ~/.bashrc,加入以下内容:

# export the Editor
export EDITOR="vim"

代码是从 Debian 系统中直接拷贝出来的,删去了一些和 OS X 没有半点关系的内容。我没有仔细研究 bashrc 的配置,只是这段足够开启彩色模式而已。

此外最后一行 export EDITOR="vim" 是我的个人习惯。

最后是解决终端白底黑字的配色问题。个人推荐使用 Smyck 这个配色。安装此配色,然后在 Terminal.app 的配置中设置为默认。如果喜欢磨砂透明,可以调整其背景的透明度和模糊程度。

最后得到的终端效果为:
