Linux FAQ: How do I show Linux disk space information? (Also stated as, What is the Linux disk space command?)

Answer: You show Linux disk space information with the Linux df command. I have a more detailed Linux df command example, but in short, I typically use the Linux df command like this, with the -h option:

df -h

The -h option stands for "human readable", and I almost always use that option instead of using the df command by itself.

This page shows the contents of the Linux du comamnd man page. This du command output was created on a CentOS Linux system.

You can see this same du command man page output by entering this command on your own Linux system:

Linux disk usage FAQ: How do I show disk usage information on a Unix or Linux system?

The Unix and Linux du command shows information about "disk usage". Whereas the df command ("disk free") shows information about Linux filesystems, the du command shows disk usage information about only the files and directories you specify.
