ncdu2 v1.0

DESCRIPTION

ncdu2 (NCurses Disk Usage) is a curses-based version of the well-known 'du', and provides a fast way to see what directories are using your disk space. ncdu2 is based on ncdu 1.14.1 at git://g.blicky.net/ncdu.git

DIFFERENCES FROM NCDU

  • Added user and groups columns. Possible to sort by users or groups as the top-level sorting.
  • Added per-user stats (total usage, items) at each directory level.
  • Always shows stats for current user on bottom status line.
  • Added option to save report with list of current view. Report also lists stats for each user for the current folder tree.
  • Added parsing of date metadata of imported index file, and shows it as [imported YYYY-MM-DD] in upper right corner.
  • Remapped key mapping, and changed many defaults compared to ncdu.
  • Not possible to disable "extended info", also completely removed internally.
  • Added NCDUZ front-end script that eases import/export of gzipped index files.

QUICK USER GUIDE

NCDU2 can be executed in three modes, 1) in-memory scan-mode (default), 2) import-mode, switch -f, 3) export-mode, switch -o. When using import or export mode, it is recommended to use NCDUZ front-end instead, because it handles compressed index files directly.

A few important NCDU2 keyboard key functions:

  • Press H to show help screen.
  • Press UP ARROW, DOWN ARROW, PAGE UP, PAGE DOWN to move between items.
  • Press ENTER or RIGHT ARROW to go to selected directory
  • Press BACKSPACE or LEFT ARROW to go to parent directory
  • Press S, C to sort items by size or count (twice toggle direction)
  • Press N, M to sort items by name or modification time
  • Press U, G to do first-order sorting by user or group (twice toggle off)
  • Press P to print report from current view, including per-user usage.

REQUIREMENTS

In order to compile and install ncdu, you need to have at least...

  • a POSIX-compliant operating system (Linux, BSD, etc)
  • curses libraries and header files

INSTALL

The usual:

./configure --prefix=/usr
make
make install

If you're building directly from the git repository, make sure you have perl (or rather, pod2man), pkg-config and GNU autoconf/automake installed, then run 'autoreconf -i', and you're ready to continue with the usual ./configure and make route.
