~8KB
Where did your disk space go? 8KB to find out.
Disk usage analyzer with sorted, human-readable output.
LinuxThe problem
"No space left on device." Every developer has seen this. The response is du -sh * | sort -rh — a command nobody types correctly on the first try. ncdu requires ncurses. Both require a runtime or shared libraries. Neither works in a stripped container.
The solution
OmniSize scans a directory and shows what is eating your disk, sorted by size, in human-readable format. One command, 8KB, instant.
Why Bare-Metal Matters
When your disk is full, the last thing you want is to install a tool to find out why. OmniSize is 8KB. Drop it anywhere. Find the problem. Delete it. Done.
