In CentOS and Ubuntu, how do I find out how much free disk space I have left and other disk stats like disk usage?

Method 1
Type the following command:
df -h
df: disk free-h: makes the output human-readable
Method 2
I covered this pretty extensively in a blog post titled: Command Line Tools for Analyzing Disk Usage on Fedora/CentOS/RHEL.
ncdu
It’s ncurses based, feature rich and has a nice clean interface and it works from within a shell.

- display diskspace used by files & directories within a directory
- display what’s happened since the last ran (see screenshots below)
- optionally provides links to the files, so you can also browse them
- displays entries with their size & the percentage of their parent
- ommits small files/directories
- easy browsing using the cursor-keys
- produces html files for browsing ‘offline’ afterwards
Disk Usage Analyzer (aka. Baobab)
- Single folder scan
- Remote scan
- Monitoring of Home
- Display Data in Treemaps or as Ringschart

In particular fsview is a very nice GUI. I like how it organizes the disk usage visually. It’s actually a KDE application (a plugin to Konqueror) but runs just fine under GNOME. It’s typically part of a package called kdeaddons, and shows up in the Applications menu as “File System Viewer” under Accessories.
Method 3
There are a few commands you can use like df, du, and a few more. Just man a few commands to find out how to use them. If you still have a problem finding what you need after that just go to any directory and do this:
sudo du --max-depth=1 | sort -nr
You’ll get something like:
2318764 ./usr 777036 ./var 328316 ./lib 222620 ./etc 86136 ./boot
Method 4
In Ubuntu dfc shows a coloured output of your mounted devices and is available via apt:
sudo apt-get install dfc
output like this:
Unfortunately this is not available for CentOS as an rpm.
