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.

I just noticed that eza can now display total disk space used by directories!

I think this is pretty cool. I wanted it for a long time.

There are other ways to get the information of course. But having it integrated with all the other options for listing directories is fab. eza has features like --git-awareness, --tree display, clickable --hyperlink, filetype --icons and other display, permissions, dates, ownerships, and other stuff. being able to mash everything together in any arbitrary way which is useful is handy. And of course you can --sort=size

docs:
  --total-size               show the size of a directory as the size of all
                             files and directories inside (unix only)
It also (optionally) color codes the information. Values measures in kb, mb, and gb are clear. Here is a screenshot to show that:
eza --long -h --total-size --sort=oldest --no-permissions --no-user
Of course it take a little while to load large directories so you will not want to use by default.

Looks like it was first implemented Oct 2023 with some fixes since then. (Changelog). PR #533 - feat: added recursive directory parser with `--total-size` flag by Xemptuous

I was talking about the 1000 vs 1024 issue, do the dd test yourself and it's easy to verify that he was right.

As for the specific descrepancy that you're seeing, lots of things can throw off a file size calculation - symlinks, sparse files, reflinks, compression etc. Since you're the only one with access to your files, you'll need to investigate and come to a conclusion yourself (and file a bug report if necessary).
