From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

We'd use
du -xh --max-depth=1|sort -hr
Interesting. Do you often deal with dirs on different filesystems?
Yeah, I was a Linux System Admin/Engineering for MLB/Disney+ for 5 years. When I was an admin, one of our tasks was clearing out filled filesystems on hosts that alerted.
Sounds pretty similar to what I do now - but never needed the -x. Guess that might be quicker when you're nested somewhere there is a bunch of nfs/smb stuff mounted in.
We'd do it from root (/) and drill down from there, it was usually /var/lib or /var/logs that was filling up, but occasionally someone would upload a 4.5 GB file to their home folder which has a quota of 5 GB.
Using ncdu would have been the best way, but that would require it being installed on about 7 thousand machines.
