我对 CLI 应用非常感兴趣，因此热衷于使用并分享 CLI 应用。 我之所以更喜欢 CLI 很大原因是因为我在大多数的时候都使用的是字符界面（black screen），已经习惯了使用 CLI 应用而不是 GUI 应用。

我写过很多关于 CLI 应用的文章。 最近我发现了一些谷歌的 CLI 工具，像 “Google Translator”、“Google Calendar” 和 “Google Contacts”。 这里，我想在给大家分享一下。

今天我们要介绍的是 “Google Translator” 工具。 由于我的母语是泰米尔语，我在一天内用了很多次才理解了它的意义。

谷歌翻译为其它语系的人们所广泛使用。

什么是 Translate Shell

Translate Shell (之前叫做 Google Translate CLI) 是一款借助谷歌翻译（默认）、必应翻译、Yandex.Translate 以及 Apertium 来翻译的命令行翻译器。它让你可以在终端访问这些翻译引擎。 Translate Shell 在大多数 Linux 发行版中都能使用。

如何安装 Translate Shell

有三种方法安装 Translate Shell。

• 下载自包含的可执行文件
• 手工安装
• 通过包管理器安装

方法 1 : 下载自包含的可执行文件

下载自包含的可执行文件放到 /usr/bin 目录中。

$ wget git.io/trans
$ chmod +x ./trans
$ sudo mv trans /usr/bin/

方法 2 : 手工安装

克隆 Translate Shell 的 GitHub 仓库然后手工编译。

$ git clone https://github.com/soimort/translate-shell && cd translate-shell
$ make
$ sudo make install

方法 3 : 通过包管理器

有些发行版的官方仓库中包含了 Translate Shell，可以通过包管理器来安装。

对于 Debian/Ubuntu， 使用 APT-GET 命令 或者 APT 命令来安装。

$ sudo apt-get install translate-shell

对于 Fedora, 使用 DNF 命令 来安装。

$ sudo dnf install translate-shell

对于基于 Arch Linux 的系统, 使用 Yaourt 命令 或 Packer 明快 来从 AUR 仓库中安装。

$ yaourt -S translate-shell
or
$ packer -S translate-shell

如何使用 Translate Shell

安装好后，打开终端闭关输入下面命令。 谷歌翻译会自动探测源文本是哪种语言，并且在默认情况下将之翻译成你的 locale 所对应的语言。

$ trans [Words]

下面我将泰米尔语中的单词 “நன்றி” (Nanri) 翻译成英语。 这个单词的意思是感谢别人。

$ trans நன்றி

(Naṉṟi)

Thanks

简洁模式：默认情况下，Translate Shell 尽可能多的显示翻译信息。如果你希望只显示简要信息，只需要加上 -b选项。

$ trans -b :ta thanks
நன்றி

字典模式：加上 -d 可以把 Translate Shell 当成字典来用。

$ trans -d :en thanks
