How to find a file on a Linux VPS
|
||||
============================================================
|
||||
|
||||
|
||||
|
||||
Using the command line on a Linux machine could be very uncomfortable, especially for the beginners. Without a GUI it is very difficult to navigate through the directories and find the files you need. In this tutorial, we will show you how to find a specific file if you are using [Linux VPS][1].
|
||||
|
||||
The first thing your need to do is to [connect to your Linux VPS via SSH][2]. There are two common ways to search for a file under Linux. The one way is to use the `find` command and the other way is to use the `locate` command. Let’s start with the former.
|
||||
|
||||
### Find command
|
||||
|
||||
The Linux find command allows you to search the directory tree using various search criteria such as name, type, ownership, size etc. This is the basic syntax:
|
||||
|
||||
```
|
||||
# find path expression search-term
|
||||
```
|
||||
|
||||
Here is a brief example on how to use the Linux find command to find a specific file by its name:
|
||||
|
||||
```
|
||||
# find -name test.file
|
||||
```
|
||||
|
||||
The command will search the entire directory tree for a file named `test.file` and will provide you with the location. You can try using a name of a file that actually exists on your Linux VPS.
|
||||
|
||||
Sometimes it may take few minutes for the find command to search the entire directory tree, especially if there are many files and directories on your system. To save a significant amount of time you can specify the searching directory. For example, if you know that the `test.file` is somewhere in the `/var` directory, there is no need to search other directories. Therefore, you can use the command below:
|
||||
|
||||
```
|
||||
# find /var -name test.file
|
||||
```
|
||||
|
||||
There is also an option to search for a file by time, size, ownership, permissions etc. For more information about these options, you can check the Linux find command man page.
|
||||
|
||||
```
|
||||
# man find
|
||||
```
|
||||
|
||||
### Locate command
|
||||
|
||||
In order to be able to use the Linux `locate` command, you need to install it first.
|
||||
|
||||
If you are using an [Ubuntu VPS][3], run the following commands to install locate:
|
||||
|
||||
```
|
||||
# apt-get update
|
||||
# apt-get install mlocate
|
||||
```
|
||||
|
||||
If you are using a [CentOS VPS][4], run the following command to install locate:
|
||||
|
||||
```
|
||||
# yum install mlocate
|
||||
```
|
||||
|
||||
Locate is a faster option to find a file since it searches for the files in a database. To update the search databases run the following command:
|
||||
|
||||
```
|
||||
# updatedb
|
||||
```
|
||||
|
||||
To find files with locate, use the following syntax:
|
||||
|
||||
```
|
||||
# locate test.file
|
||||
```
|
||||
|
||||
Just like with the find command, there are many options to filter the search output. To learn more about this you can check the Linux locate command man page.
|
||||
|
||||
```
|
||||
# man locate
|
||||
```
|
||||
|
||||

Of course, you don’t have to do any of this if you use one of our[ Linux VPS hosting][5] services, in which case you can simply ask our expert Linux admins to help you. They are available 24×7 and will take care of your request immediately.

如何在Linux VPS中查找一个文件
|
||||
============================================================
|
||||
|
||||
|
||||
|
||||
尤其对于新手而言，在linux中使用命令行可能会非常不舒服。没有GUI将很难在不同的文件夹之间寻找所要的文件。本篇教程中，我会向你展示在[Linux VPS][1]中查找特定的文件。
|
||||
|
||||
第一步要做的是[通过SSH连接到你的Linux VPS][2]。在Linux中查找文件有两种方法。一种是使用`find`命令，另外一种是使用`locate`命令。先让我们试前一种。
|
||||
|
||||
### find命令
|
||||
|
||||
Linux find命令能让你使用不同的搜索标准如名字、类型、所属人、大小等搜索目录树。这是基本的语法：
|
||||
|
||||
```
|
||||
# find path expression search-term
|
||||
```
|
||||
|
||||
下面是使用find命令根据文件名来查找特定文件的一个例子：
|
||||
|
||||
```
|
||||
# find -name test.file
|
||||
```
|
||||
|
||||
命令会搜索整个目录树来查找名为`test.file`的文件，并且会提供位置。你可以使用你VPS上一个存在的文件名来尝试一下。
|
||||
|
||||
find命令有时会花费几分钟来查找整个目录树，尤其是如果系统中有很多文件和目录的话。要明显减少时间，你可以指定搜索的目录。比如，如果你知道`/var`中存在`test.file`, 那就没有必要搜索其他目录。这样，你可以使用下面的命令：
|
||||
|
||||
```
|
||||
# find /var -name test.file
|
||||
```
|
||||
|
||||
find也有根据时间、大小、所属人、权限搜索的选项。要了解更多关于这些选项的信息，你可以使用查看find的手册。
|
||||
|
||||
```
|
||||
# man find
|
||||
```
|
||||
|
||||
### locate命令
|
||||
|
||||
要在Linux中使用`locate`命令，你首先需要安装它。
|
||||
|
||||
如果你正在使用[Ubuntu VPS][3]，运行下面的命令来安装locate：
|
||||
|
||||
```
|
||||
# apt-get update
|
||||
# apt-get install mlocate
|
||||
```
|
||||
|
||||
如果你使用的是[CentOS VPS][4]，运行下面的命令来安装locate：
|
||||
|
||||
```
|
||||
# yum install mlocate
|
||||
```
|
||||
|
||||
locae是一种比find更快的方式，因为它在数据库中查找文件。要更新搜索数据库，运行下面的命令：
|
||||
|
||||
```
|
||||
# updatedb
|
||||
```
|
||||
|
||||
要使用locate查找文件，使用下面的语法：
|
||||
|
||||
```
|
||||
# locate test.file
|
||||
```
|
||||
|
||||
就像find命令一样，locate也有很多选项来过滤输出。要了解更多你可以查看locate的手册。
|
||||
|
||||
```
|
||||
# man locate
|
||||
```
|
||||
|
||||

||||

||||
当然，如果你使用了我们的[Linux VPS托管服务][5]，你不必自己这么做，你可以请求我们专业的Linux管理员来帮助你。我们是24x7服务的，并且会立即处理你的请求。
