analyze-du - analyze the output of \du .


version 0.2.1


This analyzes the output of \du . looking for directories with a certain prefix, a certain depth and possibly sorting the output by size. It aims to aid in finding the most space-consuming components in the directory tree on the disk.

One can specify the filename as the last argument, or using the environment variable ANALYZE_DU_INPUT_FN . If none of them are specified, it defaults to using the standard input (STDIN).


analyze-du --prefix=progs/ --depth=1 --sort analyze-du -p progs/ -d


--prefix | -p

This specifies a prefix for the directories according which to filter them.

--depth | -d

This specifies a depth of the directories and their component numbers.

Defaults to 1.


When specified, this option instructs not to sort the items according to their size.

--help -h
