How to check free disk space in Linux

Keeping track of disk utilization information is on system administrators' (and others') daily to-do list. Linux has a few built-in utilities that help provide that information.
|
||||
|
||||
### df
|
||||
|
||||
The `df` command stands for "disk-free," and shows available and used disk space on the Linux system.
|
||||
|
||||
`df -h` shows disk space in human-readable format
|
||||
|
||||
`df -a` shows the file system's complete disk usage even if the Available field is 0
|
||||
![](https://opensource.com/sites/default/files/uploads/df-ha.png)
|
||||
`df -T` shows the disk usage along with each block's filesystem type (e.g., xfs, ext2, ext3, btrfs, etc.)
|
||||
|
||||
`df -i` shows used and free inodes
|
||||
![](https://opensource.com/sites/default/files/uploads/df-ti.png)
|
||||
|
||||
### du
|
||||
|
||||
`du` shows the disk usage of files, folders, etc. in the default kilobyte size
|
||||
|
||||
`du -h` shows disk usage in human-readable format for all directories and subdirectories
|
||||
|
||||
`du -a` shows disk usage for all files
|
||||
|
||||
`du -s` provides total disk space used by a particular file or directory
|
||||
![](https://opensource.com/sites/default/files/uploads/du-has.png)
|
||||
|
||||
The following commands will check your total space and your utilized space.
|
||||
|
||||
### ls -al
|
||||
|
||||
`ls -al` lists the entire contents, along with their size, of a particular directory
|
||||
![](https://opensource.com/sites/default/files/uploads/ls-al.png)
|
||||
|
||||
### stat
|
||||
|
||||
`stat <file/directory> `displays the size and other stats of a file/directory or a filesystem.
|
||||
![](https://opensource.com/sites/default/files/uploads/stat.png)
|
||||
|
||||
### fdisk -l
|
||||
|
||||
`fdisk -l` shows disk size along with disk partitioning information
|
||||
![](https://opensource.com/sites/default/files/uploads/fdisk.png)
|
||||
|
||||
These are most of the built-in utilities for checking file space in Linux. There are many similar tools, like [Disks][1] (GUI), [Ncdu][2], etc., that also show disk space utilization. Do you have a favorite tool that's not on this list? Please share in the comments.

如何检查 Linux 中的可用磁盘空间
|
||||
======
|
||||

跟踪磁盘利用率信息是系统管理员(和其他人)的日常待办事项列表之一。Linux 有一些内置的使用程序来帮助提供这些信息。
|
||||
|
||||
### df
|
||||
|
||||
`df` 命令意思是 “disk-free”,显示 Linux 系统上可用和已使用的磁盘空间。
|
||||
|
||||
`df -h` 以人类可读的格式显示磁盘空间。
|
||||
|
||||
`df -a` 显示文件系统的完整磁盘使用情况,即使 Available(可用) 字段为 0
|
||||
![](https://opensource.com/sites/default/files/uploads/df-ha.png)
|
||||
|
||||
`df -T` 显示磁盘使用情况以及每个块的文件系统类型(例如,xfs, ext2, ext3, btrfs 等)
|
||||
|
||||
`df -i` 显示已使用和未使用的 inodes
|
||||
![](https://opensource.com/sites/default/files/uploads/df-ti.png)
|
||||
|
||||
### du
|
||||
|
||||
`du` 显示文件,目录等的磁盘使用情况,默认情况下以 kb 为单位显示
|
||||
|
||||
`du -h` 以人类可读的方式显示所有目录和子目录的磁盘使用情况
|
||||
|
||||
`du -a` 显示所有文件的磁盘使用情况
|
||||
|
||||
`du -s` 提供特定文件或目录使用的总磁盘空间
|
||||
![](https://opensource.com/sites/default/files/uploads/du-has.png)
|
||||
|
||||
以下命令将检查 Linux 系统的总空间和使用空间。
|
||||
|
||||
### ls -al
|
||||
|
||||
`ls -al` 列出了特定目录的全部内容及大小。
|
||||
![](https://opensource.com/sites/default/files/uploads/ls-al.png)
|
||||
|
||||
### stat
|
||||
|
||||
`stat <文件/目录> `显示文件/目录或文件系统的大小和其他统计信息。
|
||||
![](https://opensource.com/sites/default/files/uploads/stat.png)
|
||||
|
||||
### fdisk -l
|
||||
|
||||
`fdisk -l` 显示磁盘大小以及磁盘分区信息。
|
||||
![](https://opensource.com/sites/default/files/uploads/fdisk.png)
|
||||
|
||||
这些是用于检查 Linux 文件空间的大多数内置实用程序。有许多类似的工具,如 [Disks][1](GUI 工具),[Ncdu][2] 等,它们也显示磁盘空间的利用率。你有你最喜欢的工具而它不在这个列表上吗?请在评论中分享。
