"du" - Display Disk Usage of Directories
This section provides a tutorial example on how to use 'du' command to display disk usage of any given directories on Linux systems.
To see how much disk space is used by a given directory, you can use the "du" command. Here are some sample outputs of the "du" command on my CentOS 8 computer.
1. Display disk usage of my home directory using "du":
herong$ du ~ 124876 ./ftp/files 124876 ./ftp 124880 ./work/pytorch 0 ./work/r 124884 ./work 4 ./.cache/pip/http/6/8/c/5/e 4 ./.cache/pip/http/6/8/c/5 4 ./.cache/pip/http/6/8/c ... 104 ./.cache/pip/http/c 592 ./.cache/pip/http 596 ./.cache/pip 0 ./.cache/matplotlib/tex.cache 28 ./.cache/matplotlib 624 ./.cache 0 ./.config/matplotlib 0 ./.config 4 ./.keras 250420 .
2. Display disk usage without any sub-directory entries using "du -d 0":
herong$ du -d 0 250420 .
3. Display disk usage in human readable units using "du -h":
herong$ du -d 0 -h 245M .
4. Display disk usage in units of KB, MB, or GB using "du -k|m|g":
herong$ du -d 0 -k 250420 .
