The ncdu Command

ncdu (NCurses Disk Usage) is a curses-based version of the well-known du command. It provides a fast way to see what directories are using your disk space.

Example

  1. Quiet Mode ncdu -q

  2. Omit mounted directories ncdu -q -x

Syntax

ncdu [-hqvx] [--exclude PATTERN] [-X FILE] dir

Additional Flags and their Functionalities:

Short Flag Long Flag Description
-h - Print a small help message
-q - Quiet mode. While calculating disk space, ncdu will update the screen 10 times a second by default, this will be decreased to once every 2 seconds in quiet mode. Use this feature to save bandwidth over remote connections.
-v - Print version.
-x - Only count files and directories on the same filesystem as the specified dir.
- --exclude PATTERN Exclude files that match PATTERN. This argument can be added multiple times to add more patterns.
-X FILE --exclude-from FILE Exclude files that match any pattern in FILE. Patterns should be separated by a newline.
