5 surprising things you can do with LibreOffice from the command line
|
||||
======
|
||||
Convert, print, protect, and do more with your files directly from the
|
||||
command line.
|
||||
![hot keys for shortcuts or features on computer keyboard][1]
|
||||
|
||||
LibreOffice has all the productivity features you'd want from an office software suite, making it a popular open source alternative to Microsoft Office or Google Suite. One of LibreOffice's powers is the ability to operate from the command line. For example, Seth Kenlon recently explained how he uses a global [command-line option to convert multiple files][2] from DOCX to EPUB with LibreOffice. His article inspired me to share some other LibreOffice command-line tips and tricks.
|
||||
|
||||
Before we look at some hidden features of LibreOffice commands, you need to understand how to use options with applications. Not all applications accept options (aside from the basics like the `--help` option, which works in most Linux applications).
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --help`
|
||||
```
|
||||
|
||||
This returns descriptions of other options LibreOffice accepts. Some applications don't have many options, but LibreOffice has a few screens worth, so there's plenty to play with.
|
||||
|
||||
That said, here are five useful things you can do with LibreOffice at the terminal to make the software even more useful.
|
||||
|
||||
### 1\. Customize your launch options
|
||||
|
||||
You can modify how you launch LibreOffice. For instance, if you want to open just LibreOffice's word processor component:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer #starts the word processor`
|
||||
```
|
||||
|
||||
You can open its other components similarly:
|
||||
|
||||
|
||||
```
|
||||
$ libreoffice --calc #starts the Calc document
|
||||
$ libreoffice --draw #starts an empty Draw document
|
||||
$ libreoffice --web #starts and empty HTML document
|
||||
```
|
||||
|
||||
You also can access specific help files from the command line:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --helpwriter`
|
||||
```
|
||||
|
||||
![LibreOffice Writer help][3]
|
||||
|
||||
(Don Watkins, [CC BY-SA 4.0][4])
|
||||
|
||||
Or if you need help with the spreadsheet application:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --helpcalc`
|
||||
```
|
||||
|
||||
You can start LibreOffice without the splash screen:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer --nologo`
|
||||
```
|
||||
|
||||
You can even have it launch minimized in the background while you finish working in your current window:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer --minimized`
|
||||
```
|
||||
|
||||
### 2\. Open a file in read-only mode
|
||||
|
||||
You can open files in read-only mode using `--view` to prevent accidentally making and saving changes to an important file:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --view example.odt`
|
||||
```
|
||||
|
||||
### 3\. Open a document as a template
|
||||
|
||||
Have you ever created a document to use as a letterhead or invoice form? LibreOffice has a rich built-in template system, but you can make any document a template with the `-n` option:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer -n example.odt`
|
||||
```
|
||||
|
||||
Your document will open in LibreOffice and you can make changes to it, but you won't overwrite the original file when you save it.
|
||||
|
||||
### 4\. Convert documents
|
||||
|
||||
When you need to do a small task like converting a file to a new format, it can take as long for the application to launch as it takes to do the task. The solution is the `--headless` option, which executes LibreOffice processes without launching the graphical user interface.
|
||||
|
||||
For example, converting a document to EPUB is a pretty simple task in LibreOffice—but it's even easier with the `libreoffice` command:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless --convert-to epub example.odt`
|
||||
```
|
||||
|
||||
Using wildcards means you can convert dozens of documents at once:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless --convert-to epub *.odt`
|
||||
```
|
||||
|
||||
You can convert files to several formats, including PDF, HTML, DOC, DOCX, EPUB, plain text, and many more.
|
||||
|
||||
### 5\. Print from the terminal
|
||||
|
||||
You can print LibreOffice documents from the command line without opening the application:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless -p example.odt`
|
||||
```
|
||||
|
||||
This option prints to the default printer without opening LibreOffice; it just sends the document to your printer.
|
||||
|
||||
To print all the files in a directory:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice -p *.odt`
|
||||
```
|
||||
|
||||
(More than once, I've issued this command and then run out of paper, so make sure you have enough paper loaded in your printer before you start.)
|
||||
|
||||
You can also print files to PDF. There's usually no difference between this and using the `--convert-to-pdf` option but it's easy to remember:
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --print-to-file example.odt --headless`
|
||||
```
|
||||
|
||||
### Bonus: Flatpak and command options
|
||||
|
||||
If you installed LibreOffice as a [Flatpak][5], all of these command options work, but you have to pass them through Flatpak. Here's an example:
|
||||
|
||||
|
||||
```
|
||||
`$ flatpak run org.libreoffice.LibreOffice --writer`
|
||||
```
|
||||
|
||||
It's a lot more verbose than a local install, so you might be inspired to [write a Bash alias][6] to make it easier to interact with LibreOffice directly.
|
||||
|
||||
### Surprising terminal options
|
||||
|
||||
Find out how you can extend the power of LibreOffice from the command line by consulting the man pages:
|
||||
|
||||
|
||||
```
|
||||
`$ man libreoffice`
|
||||
```
|
||||
|
||||
Were you aware that LibreOffice had such a rich set of command-line options? Have you discovered other options that nobody else seems to know about? Share them in the comments!

你可以在命令行上用 LibreOffice 做 5 件令人惊讶的事情
|
||||
======
|
||||
直接在命令行中对文件进行转换、打印、保护等操作。
|
||||
![hot keys for shortcuts or features on computer keyboard][1]
|
||||
|
||||
LibreOffice 拥有所有你想要的办公软件套件的生产力功能，使其成为微软 Office 或谷歌套件的流行的开源替代品。LibreOffice 的能力之一是可以从命令行操作。例如，Seth Kenlon 最近解释了如何使用 LibreOffice 用全局[命令行选项将多个文件][2]从 DOCX 转换为 EPUB。他的文章启发我分享一些其他 LibreOffice 命令行技巧和窍门。
|
||||
|
||||
在查看 LibreOffice 命令的一些隐藏功能之前，你需要了解如何使用应用选项。并不是所有的应用都接受选项（除了像 `--help`选项这样的基本选项，它在大多数 Linux 应用中都可以使用）。
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --help`
|
||||
```
|
||||
|
||||
这将返回 LibreOffice 接受的其他选项的描述。有些应用没有太多选项，但 LibreOffice 好几页有用的，所以有很多东西可以玩。
|
||||
|
||||
就是说，你可以在终端上使用 LibreOffice 进行以下五项有用的操作，来让使软件更加有用。
|
||||
|
||||
### 1\. 自定义你的启动选项
|
||||
|
||||
你可以修改你启动 LibreOffice 的方式。例如，如果你想只打开 LibreOffice 的文字处理器组件：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer #starts the word processor`
|
||||
```
|
||||
|
||||
你可以类似地打开它的其他组件：
|
||||
|
||||
|
||||
```
|
||||
$ libreoffice --calc #starts the Calc document
|
||||
$ libreoffice --draw #starts an empty Draw document
|
||||
$ libreoffice --web #starts and empty HTML document
|
||||
```
|
||||
|
||||
你也可以从命令行访问特定的帮助文件：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --helpwriter`
|
||||
```
|
||||
|
||||
![LibreOffice Writer help][3]
|
||||
|
||||

|
||||
|
||||
或者如果你需要电子表格应用方面的帮助：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --helpcalc`
|
||||
```
|
||||
|
||||
你可以在没有启动屏幕的情况下启动 LibreOffice：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer --nologo`
|
||||
```
|
||||
|
||||
你甚至可以在你完成当前窗口的工作时，让它在后台最小化：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer --minimized`
|
||||
```
|
||||
|
||||
### 2\. 以只读模式打开一个文件
|
||||
|
||||
你可以使用 `--view` 以只读模式打开文件，以防止意外地对重要文件进行修改和保存：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --view example.odt`
|
||||
```
|
||||
|
||||
### 3\. 打开一个模板文档
|
||||
|
||||
你是否曾经创建过用作信头或发票表格的文档？LibreOffice 具有丰富的内置模板系统，但是你可以使用 -n 选项将任何文档作为模板：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --writer -n example.odt`
|
||||
```
|
||||
|
||||
你的文档将在 LibreOffice 中打开，你可以对其进行修改，但保存时不会覆盖原始文件。
|
||||
|
||||
### 4\. 转换文档
|
||||
|
||||
当你需要做一个小任务，比如将一个文件转换为新的格式时，应用启动的时间可能与完成任务的时间一样长。解决办法是 `--headless` 选项，它可以在不启动图形用户界面的情况下执行 LibreOffice 进程。
|
||||
|
||||
例如，在 LibreOffic 中，将一个文档转换为 EPUB 是一个非常简单的任务，但使用 `libreoffice` 命令就更容易：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless --convert-to epub example.odt`
|
||||
```
|
||||
|
||||
使用通配符意味着你可以一次转换几十个文档：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless --convert-to epub *.odt`
|
||||
```
|
||||
|
||||
你可以将文件转换为多种格式，包括 PDF、HTML、DOC、DOCX、EPUB、纯文本等。
|
||||
|
||||
### 5\. 从终端打印
|
||||
|
||||
你可以从命令行打印 LibreOffice 文档，而无需打开应用：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --headless -p example.odt`
|
||||
```
|
||||
|
||||
这个选项不需要打开 LibreOffice 就可以使用默认打印机打印，它只是将文档发送到你的打印机。
|
||||
|
||||
要打印一个目录中的所有文件：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice -p *.odt`
|
||||
```
|
||||
|
||||
|
||||
（我不止一次执行了这个命令，然后用完了纸，所以在你开始之前，确保你的打印机里有足够的纸张。)
|
||||
|
||||
|
||||
你也可以把文件输出成 PDF。通常这和使用 `--convert-to-pdf` 选项没有什么区别，但是很容易记住：
|
||||
|
||||
|
||||
```
|
||||
`$ libreoffice --print-to-file example.odt --headless`
|
||||
```
|
||||
|
||||
### 额外技巧：Flatpak 和命令选项
|
||||
|
||||
如果你使用 [Flatpak][5] 安装 LibreOffice，所有这些命令选项都可以使用，但你必须通过 Flatpak 传递。下面是一个例子：
|
||||
|
||||
|
||||
```
|
||||
`$ flatpak run org.libreoffice.LibreOffice --writer`
|
||||
```
|
||||
|
||||
它比本地安装要麻烦得多，所以你可能会受到启发[写一个 Bash 别名][6]来使它更容易直接与 LibreOffice 交互。
|
||||
|
||||
### 令人惊讶的终端选项
|
||||
|
||||
通过查阅手册页面，了解如何从命令行扩展 LibreOffice 的功能：
|
||||
|
||||
|
||||
```
|
||||
`$ man libreoffice`
|
||||
```
|
||||
|
||||
你是否知道 LibreOffice 具有如此丰富的命令行选项？ 你是否发现了其他人似乎都不了解的其他选项？ 请在评论中分享它们！
