To check the available disk space in Linux

To check the available disk space in Linux in a readable format, you can use the df command with the -h option, which will display the sizes in a human-readable format (e.g., megabytes or gigabytes). Here’s how to use it:

Open your terminal and type the following command:

df -h

This command will display a list of all mounted filesystems along with their respective disk usage and available space in a human-readable format.

Here’s an example of what the output might look like:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        20G   7.5G   11G  41% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
/dev/sdb1        50G   20G   28G  42% /data

In this example, you can see the filesystem, its total size (Size), the used space (Used), the available space (Avail), the percentage of space used (Use%), and the mount point (Mounted on). The -h flag makes the sizes more human-friendly by using units like gigabytes (G) and megabytes (M).
