This article is to share with you about what commands are used by linux to view disk space. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

In linux, you can use the df command to view disk space. The df command can be used to check disk footprint, or disk usage, in the Linux file system.

Grammar

Df [options]... [FILE]...

Command parameters:

●-a,-- all contains all systems with 0 Blocks

●-- block-size= {SIZE} uses a Blocks of {SIZE} size

●-h,-- human-readable uses a human-readable format (the default value is not added with this option.)

●-H,-- si is a lot like-h, but in units of 1000 instead of 1024

●-I,-- inodes lists inode information, not block used

●-k,-- kilobytes is like-- block-size=1024.

●-l,-- local restricts the file structures listed

●-m,-- megabytes is like-- block-size=1048576

●-- no-sync does not sync before obtaining information (default)

●-P,-- portability uses the POSIX output format

●-- sync sync before obtaining the information

●-t,-- type=TYPE limits the TYPE that lists the file system

●-T,-- print-type displays the form of the file system

●-x,-- exclude-type=TYPE restricts listing file systems and does not display TYPE

●-v (ignore)

●-- help shows the helper and leaves

●-- version outputs version information and leaves

How do I use the df command to view disk space?

"if used without any parameters, the df command displays information about all mounted file systems:"

# df

Output:

Filesystem 1K-blocks Used Available Use% Mounted ondev 8172848 0 8172848 / devrun 8218640 1696 8216944 1% / run/dev/nvme0n1p3 222284728 183057872 27865672 87% / tmpfs 8218640 150256 80683842 / dev/shm/dev/nvme0n1p1 523248 107912 415336 21% / boot/dev/sda1 480588496 172832632 283320260 38% / data

Each line includes information about the file system name (Filesystem), size (1K-blocks), used space (Used), free space (Available), percentage of used space (Use%), and information about the directory in it that the file system is mounted (Mounted on).

By default, the df command displays disk space in 1 KB and the amount of used and available disk space in kilobytes. This is very inconvenient, how to display disk space usage in human-readable formats (megabytes and gigabytes)?

To view information in human-readable formats (megabytes and gigabytes), you need to pass the following-h option:

# df-h

Output:

Filesystem 1K-blocks Used Available Use% Mounted onFilesystem Size Used Avail Use% Mounted ondev 7.8G 0 7.8G 0% / devrun 7.9G 1.8m 7.9G 1% / run/dev/nvme0n1p3 212G 176G 27G 88% / tmpfs 7.9G 145m 7.7G 2% / dev/shm/dev/nvme0n1p1 511M 106M 406M 21% / boot/dev/sda1 459G 165G 271G 38% / data Thank you for your reading!
