rapiDU

A much faster du that tells you why your quota is full.

Install

pip install rapidu

Use

rdu                      # this directory: how big, and what is big inside it
rdu /project/mylab       # any other path
rdu ~/scratch -n 20      # list 20 entries instead of 10

rdu -i                   # rank by file count -- what an inode quota limits
rdu -c                   # count files only, no stat: ~8x again on GPFS
rdu -Q                   # the quota table, and the age of its figures
rdu -D                   # space held by files deleted while still open
rdu -a                   # the full audit: quota + /proc scan + reconciliation

Faster, and the same number

Same total as du, to the byte. That is checked on every commit.

The frame carries no title and it always closes: a line too wide for it wraps inside, at a path separator, rather than running past the border. Its colour is a gradient sweeping from the top-left corner, and it degrades — 24-bit if your terminal advertises COLORTERM=truecolor, a 12-step ramp at 256 colours, and a calm three-step cyan at 8. --ascii turns it into +--+; --no-box removes it, which is what you want when piping into grep or a diff.

share labels the bar and the percentage beside it: they are one measurement in two forms, the picture and the number. The bar is share of the whole walk, so it always agrees with the number beside it. The hatched row is everything not listed. The column you sorted by is the one in colour — under -i, files takes the tone and size steps back. Sizes are cumulative, so any row agrees with du -s on that path.
