Disk usage statistics in linux

In Linux, you can use various commands and tools to obtain disk usage statistics, like df or du.

df command

The df command provides information about file system disk space usage on Linux systems. By default, it displays disk usage in kilobytes (KB), but you can specify different units if needed. Here’s the basic usage:

df -h

du command

du Command: The du command is used to estimate file and directory sizes. It recursively traverses directories and reports the disk usage of each file and directory. Here’s an example of how to use it:

Check single directory.

du -sh /var

Check all elements in a path

du -shc /var/*

Check all elements include one level sub-directory in a path

du -h --max-depth=1 /var

Sort by size and list top 5

du -h /var/ | sort -rh | head -5
