应用启动器可以让你快速访问或打开一个应用，而无需在应用菜单图标上徘徊。


在默认情况下，我发现 Pop!\_OS 的应用启动器超级方便。但是，并不是每个 Linux 发行版都提供开箱即用的应用启动器。


幸运的是，有一个你可以在大多数流行的发行版中添加应用启动器的方案。


### Ulauncher：开源应用启动器


![](/data/attachment/album/202109/01/223959i21566f0h0f03qz3.png)


Ulauncher 是一个使用 Python 还有 GTK+ 构建的快速应用启动器。


它提供了相当数量的自定义和控制选项来进行调整。总的来说，你可以调整它的行为和体验以适应你的喜好。


让我来说一下你可以期待它的一些功能。


### Ulauncher 功能


Ulauncher 中的选项非常非常易于访问且易于定制。一些关键的亮点包括：


* 模糊搜索算法可以让你即使拼错了，也能找到应用
* 可以记住你在同一会话中最后搜索的应用
* 显示经常使用的应用（可选）
* 自定义颜色主题
* 预设颜色主题，包括一个黑暗主题
* 召唤启动器的快捷方式可以轻松定制
* 浏览文件和目录
* 支持扩展，以获得额外的功能（表情符号、天气、速度测试、笔记、密码管理器等）
* 浏览谷歌、维基百科和 Stack Overflow 等网站的快捷方式


它几乎提供了你在一个应用启动器中所期望的所有有用的能力，甚至更好。


### 如何在 Linux 中使用 Ulauncher？


默认情况下，首次从应用菜单中打开应用启动器后，你需要按 `Ctrl + Space` 打开应用启动器。


输入以搜索一个应用。如果你正在寻找一个文件或目录，输入以 `~` 或者 `/` 开始。

有一些默认的快捷键，如 `g XYZ`，其中 “XYZ” 是你想在谷歌中搜索的搜索词。

同样，你可以通过 `wiki` 和 `so` 快捷键，直接在维基百科或 Stack Overflow 搜索。


在没有任何扩展的情况下，你也可以直接计算内容，并将结果直接复制到剪贴板。


![](/data/attachment/album/202109/01/224005fdrsy27s7riusyf1.png)


这在快速计算时应该很方便，不需要单独启动计算器应用。


你可以前往它的 [扩展页面](https://ext.ulauncher.io)，浏览有用的扩展，以及指导你如何使用它的截图。


要改变它的工作方式，启用显示经常使用的应用，并调整主题，请点击启动器右侧的齿轮图标。

你可以把它设置为自动启动。但是，如果它在你的支持 Systemd 的发行版上不工作，你可以参考它的 GitHub 页面，把它添加到服务管理器中。


这些选项是非常直观，且易于定制，如下图所示。

### 在 Linux 中安装 Ulauncher


Ulauncher 为基于 Debian 或 Ubuntu 的发行版提供了一个 deb 包。如果你是 Linux 新手，你可以了解一下 [如何安装 Deb 文件](https://itsfoss.com/install-deb-files-ubuntu/) 。


在这两种情况下，你也可以添加它的 PPA，并通过终端按照下面的命令来安装它：



```
sudo add-apt-repository ppa:agornostal/ulauncher
sudo apt update
sudo apt install ulauncher

```

你也可以在 [AUR](https://itsfoss.com/aur-arch-linux/) 中找到它，用于 Arch 和 Fedora 的默认仓库。


对于更多信息，你可以前往其官方网站或 [GitHub 页面](https://github.com/Ulauncher/Ulauncher/)。

Ulauncher 应该是任何 Linux 发行版中一个令人印象深刻的补充。特别是，如果你想要一个像 Pop!\_OS 提供的快速启动器的功能，这是一个值得考虑的奇妙选择。

OK
*Brief: **Ulauncher is a fast application launcher with extension and shortcut support to help you quickly access application and files in Linux.*

An application launcher lets you quickly access or open an app without hovering over the application menu icons.

By default, I found the application launcher with Pop!_OS super handy. But, not every Linux distribution offers an application launcher out-of-the-box.

Fortunately, there is a solution with which you can add the application launcher to most of the popular distros out there.

## Ulauncher: Open Source Application Launcher

![ulauncher](https://itsfoss.com/content/images/wordpress/2021/08/ulauncher-800x512.png)

Ulauncher is a quick application launcher built using Python while utilizing GTK+.

It gives a decent amount of customization and control options to tweak. Overall, you can adjust its behavior and experience to suit your taste.

Let me highlight some of the features that you can expect with it.

## Ulauncher Features

The options that you get with Ulauncher are super accessible and easy to customize. Some key highlights include:

- Fuzzy search algorithm, which lets you find applications even if you misspell them
- Remembers your last searched application in the same session
- Frequently used apps display (optional)
- Custom color themes
- Preset color themes that include a dark theme
- Shortcut to summon the launcher can be easily customized
- Browse files and directories
- Support for extensions to get extra functionality (emoji, weather, speed test, notes, password manager, etc.)
- Shortcuts for browsing sites like Google, Wikipedia, and Stack Overflow

It provides almost every helpful ability that you may expect in an application launcher, and even better.

## How to Use Ulauncher in Linux?

By default, you need to press **Ctrl + Space** to get the application launcher after you open it from the application menu for the first time.

Start typing in to search for an application. And, if you are looking for a file or directory, start typing with “**~**” or “**/**” (ignoring the quotes).

![ulauncher directory](https://itsfoss.com/content/images/wordpress/2021/08/ulauncher-directory.png)

There are default shortcuts like “**g XYZ**” where XYZ is the search term you want to search for in Google.

![ulauncher google](https://itsfoss.com/content/images/wordpress/2021/08/ulauncher-google.png)

Similarly, you can search for something directly taking you to Wikipedia or Stack Overflow, with “**wiki**” and “**so**” shortcuts, respectively.

Without any extensions, you can also calculate things on the go and copy the results directly to the keyboard.

![ulauncher calculator](https://itsfoss.com/content/images/wordpress/2021/08/ulauncher-calculator.png)

This should come in handy for quick calculations without needing to launch the calculator app separately.

You can head to its [extensions page](https://ext.ulauncher.io) and browse for useful extensions along with screenshots that should instruct you how to use it.

To change how it works, enable frequent applications display, and adjust the theme — click on the gear icon on the right side of the launcher.

![ulauncher gear icon](https://itsfoss.com/content/images/wordpress/2021/08/ulauncher-gear-icon.png)

You can set it to auto-start. But, if it does not work on your Systemd enabled distro, you can refer to its GitHub page to add it to the service manager.

The options are self-explanatory and are easy to customize, as shown in the screenshot below.

## Installing Ulauncher in Linux

Ulauncher provides a **.deb** package for Debian or Ubuntu-based distributions. You can explore [how to install Deb ](https://itsfoss.com/install-deb-files-ubuntu/)[f](https://itsfoss.com/install-deb-files-ubuntu/)[iles](https://itsfoss.com/install-deb-files-ubuntu/) if you’re new to Linux.

In either case, you can also add its PPA and install it via terminal by following the commands below:

```
sudo add-apt-repository ppa:agornostal/ulauncher
sudo apt update
sudo apt install ulauncher
```


You can also find it available in the [AUR](https://itsfoss.com/aur-arch-linux/) for Arch and Fedora’s default repositories.

For more information, you can head to its official website or the [GitHub page](https://github.com/Ulauncher/Ulauncher/).

Ulauncher should be an impressive addition to any Linux distro. Especially, if you want the functionality of a quick launcher like Pop!_OS offers, this is a fantastic option to consider.
