A friendly alternative to the find tool in Linux
|
||||
======
|
||||
|
||||
|
||||
[fd][1] is a super fast, [Rust][2]-based alternative to the Unix/Linux `find` command. It does not mirror all of `find`'s powerful functionality; however, it does provide just enough features to cover 80% of the use cases you might run into. Features like a well thought-out and convenient syntax, colorized output, smart case, regular expressions, and parallel command execution make `fd` a more than capable successor.
|
||||
|
||||
### Installation
|
||||
|
||||
Head over the [fd][1] GitHub page and check out the section on installation. It covers how to install the application on [macOS,][3] [Debian/Ubuntu][4] [Red Hat][5] , and [Arch Linux][6] . Once installed, you can get a complete overview of all available command-line options by runningfor concise help, or `fd -h` for concise help, or `fd --help` for more detailed help.
|
||||
|
||||
### Simple search
|
||||
|
||||
`fd` is designed to help you easily find files and folders in your operating system's filesystem. The simplest search you can perform is to run `fd` with a single argument, that argument being whatever it is that you're searching for. For example, let's assume that you want to find a Markdown document that has the word `services` as part of the filename:
|
||||
```
|
||||
$ fd services
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
If called with just a single argument, `fd` searches the current directory recursively for any files and/or directories that match your argument. The equivalent search using the built-in `find` command looks something like this:
|
||||
```
|
||||
$ find . -name 'services'
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
As you can see, `fd` is much simpler and requires less typing. Getting more done with less typing is always a win in my book.
|
||||
|
||||
### Files and folders
|
||||
|
||||
You can restrict your search to files or directories by using the `-t` argument, followed by the letter that represents what you want to search for. For example, to find all files in the current directory that have `services` in the filename, you would use:
|
||||
```
|
||||
$ fd -tf services
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
And to find all directories in the current directory that have `services` in the filename:
|
||||
```
|
||||
$ fd -td services
|
||||
|
||||
applications/services
|
||||
|
||||
library/services
|
||||
|
||||
```
|
||||
|
||||
How about listing all documents with the `.md` extension in the current folder?
|
||||
```
|
||||
$ fd .md
|
||||
|
||||
administration/administration.md
|
||||
|
||||
development/elixir/elixir_install.md
|
||||
|
||||
readme.md
|
||||
|
||||
sidebar.md
|
||||
|
||||
linux.md
|
||||
|
||||
```
|
||||
|
||||
As you can see from the output, `fd` not only found and listed files from the current folder, but it also found files in subfolders. Pretty neat. You can even search for hidden files using the `-H` argument:
|
||||
```
|
||||
fd -H sessions .
|
||||
|
||||
.bash_sessions
|
||||
|
||||
```
|
||||
|
||||
### Specifying a directory
|
||||
|
||||
If you want to search a specific directory, the name of the directory can be given as a second argument to `fd`:
|
||||
```
|
||||
$ fd passwd /etc
|
||||
|
||||
/etc/default/passwd
|
||||
|
||||
/etc/pam.d/passwd
|
||||
|
||||
/etc/passwd
|
||||
|
||||
```
|
||||
|
||||
In this example, we're telling `fd` that we want to search for all instances of the word `passwd` in the `etc` directory.
|
||||
|
||||
### Global searches
|
||||
|
||||
What if you know part of the filename but not the folder? Let's say you downloaded a book on Linux network administration but you have no idea where it was saved. No problem:
|
||||
```
|
||||
fd Administration /
|
||||
|
||||
/Users/pmullins/Documents/Books/Linux/Mastering Linux Network Administration.epub
|
||||
|
||||
```
|
||||
|
||||
### Wrapping up
|
||||
|
||||
The `fd` utility is an excellent replacement for the `find` command, and I'm sure you'll find it just as useful as I do. To learn more about the command, simply explore the rather extensive man page.

Linux 中一种友好的 find 替代工具
|
||||
======
|
||||
|
||||
|
||||
[fd][1] 是一个超快的，基于 [Rust][2] 的 Unix/Linux `find` 命令的替代。它不提供所有 `find` 的强大功能。但是，它确实提供了足够的功能来覆盖可能遇到的 80％ 的情况。诸如良好的规划和方便的语法、彩色输出、智能大小写、正则表达式以及并行命令执行等特性使 `fd` 成为一个非常有能力的后继者。
|
||||
|
||||
### 安装
|
||||
|
||||
进入 [fd][1] GitHub 页面，查看安装部分。它涵盖了如何在[macOS][3]、 [Debian/Ubuntu][4] [Red Hat][5] 和 [Arch Linux][6] 上安装程序。安装完成后，你可以通过运行帮助来获得所有可用命令行选项的完整概述，通过 `fd -h` 获取简明帮助，或者通过 `fd --help` 获取更详细的帮助。
|
||||
|
||||
### 简单搜索
|
||||
|
||||
`fd` 旨在帮助你轻松找到文件系统中的文件和文件夹。你可以用 `fd` 带上一个参数执行最简单的搜索，该参数就是你要搜索的任何东西。例如，假设你想要找一个 Markdown 文档，其中包含单词 `services` 作为文件名的一部分：
|
||||
```
|
||||
$ fd services
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
如果仅带一个参数调用，那么 `fd` 递归地搜索当前目录以查找与莫的参数匹配的任何文件和/或目录。使用内置的 `find` 命令的等效搜索如下所示：
|
||||
```
|
||||
$ find . -name 'services'
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
如你所见，`fd` 要简单得多，并需要更少的输入。在我心中用更少的输入做更多的事情总是胜利的。
|
||||
|
||||
### 文件和文件夹
|
||||
|
||||
您可以使用 `-t` 参数将搜索范围限制为文件或目录，后面跟着代表你要搜索的内容的字母。例如，要查找当前目录中文件名中包含 `services` 的所有文件，可以使用：
|
||||
```
|
||||
$ fd -tf services
|
||||
|
||||
downloads/services.md
|
||||
|
||||
```
|
||||
|
||||
并找到当前目录中文件名中包含 `services` 的所有目录：
|
||||
```
|
||||
$ fd -td services
|
||||
|
||||
applications/services
|
||||
|
||||
library/services
|
||||
|
||||
```
|
||||
|
||||
如何在当前文件夹中列出所有带 `.md` 扩展名的文档？
|
||||
```
|
||||
$ fd .md
|
||||
|
||||
administration/administration.md
|
||||
|
||||
development/elixir/elixir_install.md
|
||||
|
||||
readme.md
|
||||
|
||||
sidebar.md
|
||||
|
||||
linux.md
|
||||
|
||||
```
|
||||
|
||||
从输出中可以看到，`fd` 不仅可以找到并列出当前文件夹中的文件，还可以在子文件夹中找到文件。很简单。你甚至可以使用 `-H` 参数来搜索隐藏文件：
|
||||
```
|
||||
fd -H sessions .
|
||||
|
||||
.bash_sessions
|
||||
|
||||
```
|
||||
|
||||
### 指定目录
|
||||
|
||||
如果你想搜索一个特定的目录，这个目录的名字可以作为第二个参数传给 `fd`
|
||||
```
|
||||
$ fd passwd /etc
|
||||
|
||||
/etc/default/passwd
|
||||
|
||||
/etc/pam.d/passwd
|
||||
|
||||
/etc/passwd
|
||||
|
||||
```
|
||||
|
||||
在这个例子中，我们告诉 `fd` 我们要在 `etc` 目录中搜索 `passwd` 这个单词的所有实例。
|
||||
|
||||
### 全局搜索
|
||||
|
||||
如果你知道文件名的一部分，但不知道文件夹怎么办？假设你下载了一本关于 Linux 网络管理的书，但你不知道它的保存位置。没有问题：
|
||||
```
|
||||
fd Administration /
|
||||
|
||||
/Users/pmullins/Documents/Books/Linux/Mastering Linux Network Administration.epub
|
||||
|
||||
```
|
||||
|
||||
### 总结
|
||||
|
||||
`fd` 是 `find` 命令的极好的替代品，我相信你会和我一样发现它很有用。要了解该命令的更多信息，只需浏览手册页。
