How to view used disk space on a Linux Server

You can view the used disk space on a Linux server using the df command.

The df command provides information about the file system disk space usage, including the amount of used and available disk space for each file system on the server.

To view the used disk space on a Linux server using the df command, follow these steps:

1. Open a terminal window on the Linux server.

2. Type the following command and press Enter:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb        251G  7.6G  231G   4% /
tmpfs            13G     0   13G   0% /mnt/wsl
tools           233G  219G   15G  94% /init
none             13G     0   13G   0% /dev
none             13G   16K   13G   1% /run
none             13G     0   13G   0% /run/lock
none             13G     0   13G   0% /run/shm
none             13G     0   13G   0% /run/user
tmpfs            13G     0   13G   0% /sys/fs/cgroup
drivers         233G  219G   15G  94% /usr/lib/wsl/drivers
lib             233G  219G   15G  94% /usr/lib/wsl/lib
C:\             233G  219G   15G  94% /mnt/c
D:\             465G  445G   20G  96% /mnt/d
E:\             932G   51G  881G   6% /mnt/e

The -h option displays the disk space usage in a human-readable format, using units like "GB" or "MB" instead of raw bytes.

3. The df command will display a list of all the file systems on the server, along with their total size, used space, available space, and mount point. Look for the file system you are interested in to see its disk usage.

If you want to view the disk usage for a specific directory, you can use the du command. For example, to view the disk usage for the current directory and all its subdirectories, you can use the following command:

The -h option is again used to display the disk usage in a human-readable format.
