7 Ways to Determine the File System Type in Linux (Ext2, Ext3 or Ext4)
|
||||
Linux 中 7 个判断文件系统类型的方法（Ext2、Ext3 或者 Ext4）
|
||||
============================================================
|
||||
|
||||
|
||||
A file system is the way in which files are named, stored, retrieved as well as updated on a storage disk or partition; the way files are organized on the disk.
|
||||
文件系统是文件命名、存储、检索以及磁盘更新及分区的方式，也就是磁盘上组织文件的方式。
|
||||
|
||||
A file system is divided in two segments called: User Data and Metadata (file name, time it was created, modified time, it’s size and location in the directory hierarchy etc).
|
||||
文件系统分为两个部分：用户数据和元数据（文件名、创建时间、修改时间、大小以及目录层次结构中的位置等）。
|
||||
|
||||
In this guide, we will explain seven ways to identify your Linux file system type such as Ext2, Ext3, Ext4, BtrFS, GlusterFS plus many more.
|
||||
在本指南中，我们将用 7 中方法来识别你的 Linux 文件系统类型，如Ext2、Ext3、Ext4、BtrFS、GlusterFS 等等。
|

|
||||
### 1\. Using df Command
|
||||
### 1\. df 命令使用
|
||||
|
||||
df command reports file system disk space usage, to include the file system type on a particular disk partition, use the `-T` flag as below:
|
||||
df 命令报告文件系统磁盘空间利用率，包括特定磁盘分区的文件系统类型，像下面那样使用 `-T` 标志：
|
||||
|
||||
```
|
||||
$ df -Th
|
||||
OR
|
||||
或者
|
||||
$ df -Th | grep "^/dev"

The flag `-N` disables checking of file system for errors, it just shows what would be done (but all we need is the file system type):
|
||||
`-N 标志禁用检查文件系统错误，它只是显示会做什么（但是我们只需要文件系统类型）：
