cdu (Colour du) is a du like command but displays an attractive histogram with optional colours.
With no arguments, cdu reports the disk space for all subdirectories of the current directory. With only one directory argument, cdu reports the disk space for all subdirectories of the given directory. You can also call du with no predefined options.
This is free and open source software.
Key Features
- Option to use a logarithmic histogram.
- Show percentage instead of size.
- Show all directories and subdirectories. The size of each directory include the size of all its subdirectories. There is only one exception for the directory “.”. Its size don’t include its subdirectories (the total size is given by the “Total” line).
- Sort by size.
- Filtering options. For example, you can only display directories which size is greater than a defined amount.
