diskus is a very simple program that computes the total size of the current directory.
It is a parallelized version of du -sh.
This is free and open source software.
Key Features
- Set the number of threads. By default the program uses 3 x number of cores in the machine.
- Choose the output format for file sizes (decimal or binary).
- Option not to hide filesystem error.s
- Option to compute apparent size instead of disk usage.
- Changes its output format when the output is piped to a file or to another program. It will simply print the number of bytes.
- Custom implementation of a parallel directory walker using rayon.
- Cross-platform support – runs under Linux, macOS and Windows.
