Sometimes, you don’t need to open an image in a photo editor–you just want to make sure which file is which. Instead of opening each file, you can preview each one in Ubuntu’s file manager program, Nautilus, without opening them.
有时，您不需要在照片编辑器中打开图像-您只想确保哪个文件是哪个文件即可。 除了打开每个文件，您可以在Ubuntu的文件管理器程序Nautilus中预览每个文件，而无需打开它们。
We’ll show you how to install and use an add-in for Nautilus, called GNOME Sushi, that will allow you to preview image files, text files, PDF files, LibreOffice files, and even media files by pressing the spacebar. It’s similar to the Quick Look feature in macOS.
我们将向您展示如何为Nautilus安装和使用名为GNOME Sushi的加载项，该加载项使您可以通过按空格键预览图像文件，文本文件，PDF文件，LibreOffice文件甚至媒体文件。 它类似于macOS中的“快速查找”功能。
To install GNOME Sushi using Ubuntu Software, click the following link: apt://gnome-sushi
要使用Ubuntu软件安装GNOME Sushi，请单击以下链接： apt：// gnome-sushi
You can also copy and paste that link into the address bar in a browser and press Enter.
您也可以将该链接复制并粘贴到浏览器的地址栏中，然后按Enter。
The following dialog box displays. Click “Install”.
显示以下对话框。 点击“安装”。
The Authenticate dialog box displays. Enter the password for your Ubuntu account in the box and click “Authenticate”.
显示“身份验证”对话框。 在框中输入您的Ubuntu帐户的密码，然后单击“身份验证”。
Ubuntu will install the software and show you its progress.
Ubuntu将安装该软件并向您显示其进度。
Once GNOME Sushi is installed, open Nautilus by clicking the Files icon on the Unity bar.
安装GNOME Sushi后，通过单击Unity栏上的“文件”图标打开Nautilus。
Find a file you want to preview and select it. For our first example, we’re going to preview an image file.
找到您要预览的文件并选择它。 对于第一个示例，我们将预览图像文件。
Press the Spacebar to preview the file. A preview window shows the image and a diagonal double arrow button is available when you move the mouse cursor over the image preview. Click this double-arrow button to enlarge the image preview.
按空格键预览文件。 预览窗口显示图像，将鼠标光标移到图像预览上时，对角双箭头按钮可用。 单击此双箭头按钮可放大图像预览。
NOTE: The previewer should work immediately without logging out and back in or restarting. If not, exit Nautilus and reopen it.
注意：预览器应立即工作，而无需注销并重新登录或重新启动。 如果没有，请退出Nautilus并重新打开它。
A larger preview of the image displays, also with the double-arrow button. Clicking the double-arrow button returns you to the original preview size. Press the Spacebar or the Esc key to close the preview window.
显示图像的更大预览，也带有双箭头按钮。 单击双箭头按钮将返回到原始预览大小。 按空格键或Esc键关闭预览窗口。
Hit the Spacebar or the Esc key to close the preview window.
点击空格键或Esc键关闭预览窗口。
You can also preview text files. Again, select the text file you want to preview and press the Spacebar to preview the file.
您也可以预览文本文件。 再次，选择要预览的文本文件，然后按空格键预览该文件。
The text file opens in the preview window and you can scroll through the file using your mouse’s scroll button or the scroll bar on the right. The text does not wrap, so there is also a scroll bar on the bottom for scrolling to the end of the lines. When previewing text files, you can open them from the preview window. Click on the button at the bottom with the document icon on it. The file will open in the default text editor.
文本文件在预览窗口中打开，您可以使用鼠标的滚动按钮或右侧的滚动条滚动浏览该文件。 文本不会自动换行，因此底部还有一个滚动条，用于滚动到行尾。 预览文本文件时，可以从预览窗口中打开它们。 单击底部带有文档图标的按钮。 该文件将在默认的文本编辑器中打开。
In addition to text files, you can also view LibreOffice files. For our example, we’ll select an .odt file, which is a LibreOffice Writer file.
除了文本文件，您还可以查看LibreOffice文件。 对于我们的示例，我们将选择一个.odt文件，它是LibreOffice Writer文件。
To view a LibreOffice file, you must install an additional software package, if you don’t already have it. Click “Install” on the Install additional software package that displays.
要查看LibreOffice文件，必须安装其他软件包(如果尚未安装)。 在显示的“安装其他软件包”上单击“安装”。
Enter your password on the Authenticate dialog box and click “Authenticate”.
在“身份验证”对话框中输入密码，然后单击“身份验证”。
The Installing packages dialog box displays as the additional package is installed.
安装其他软件包后，将显示“安装软件包”对话框。
Once the additional software has been installed, the LibreOffice file displays in the preview window. For multi-page LibreOffice documents, you can scroll down through the pages of the document, or you can use the right and left page arrows. You can also enlarge the preview by clicking the diagonal double-arrow button.
一旦安装了其他软件，LibreOffice文件就会显示在预览窗口中。 对于多页的LibreOffice文档，您可以向下滚动文档的页面，也可以使用左右箭头。 您也可以通过单击对角双箭头按钮来放大预览。
To quickly preview a long list of files, you can select the first one, press the Spacebar to preview the file, press the Spacebar again to close the preview window, and then press the down arrow key to select the next file. Repeat this procedure to quickly preview one file after the other.
要快速预览一长串文件，可以选择第一个文件，按空格键预览文件，再次按空格键关闭预览窗口，然后按向下箭头键选择下一个文件。 重复此过程可以快速预览一个文件。
