How can you determine the current level of disk space usage?

To determine the current level of disk space usage on Linux/Unix systems, you can use the df (disk free) command. It displays information about file systems, including total size, used, and available space.

Example command:

df -h

The -h option displays sizes in a human-readable format (e.g., MB, GB).

The output will look approximately like this:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        50G   20G   28G  42% /

Here, you can see that a 50 GB disk is used by 20 GB, with 28 GB available, and the usage percentage is 42%.

In Windows, you can use the command wmic logicaldisk get size,freespace,caption in the command prompt or view disk properties through File Explorer.
