dutop is a command-line utility that scans the file system from a given root path and reports any the file or directory that occupies more than 5% of the space. It answers the question:
Which single file or directory should I remove to reclaim significant storage space?
Here's how to get a sense of what takes the most space in the /usr
directory:
$ dutop /usr
d 5.2% 429,055,696 /usr/local/lib/python3.5/dist-packages
d 5.2% 429,055,696 /usr/local/lib/python3.5
d 5.6% 461,789,323 /usr/lib/ghc
d 5.7% 473,685,763 /usr/share/doc
d 6.6% 549,563,745 /usr/bin
d 9.0% 743,990,153 /usr/local/lib
d 11.7% 972,273,271 /usr/local
d 16.9% 1,401,349,064 /usr/lib/x86_64-linux-gnu
d 27.7% 2,301,009,747 /usr/share
d 49.0% 4,070,197,838 /usr/lib
d 100.0% 8,309,946,131 /usr
The output is brief, since only any object representing at least 5% of
the total is shown. Compare that to du /usr which here produces
44,476 lines of output due to the large number of files. The closest
standard command would be du -s, which gives us the following:
$ du -s /usr/*
540568 /usr/bin
772 /usr/games
187364 /usr/include
4061168 /usr/lib
16880 /usr/lib32
17568 /usr/libx32
1110684 /usr/local # lacks details
20 /usr/locale # too small to be of interest
41052 /usr/sbin
2649668 /usr/share
370756 /usr/src
The granularity of dutop can be adjusted. For example, we can set it
to 3%:
$ dutop -m 0.03 /usr
d 3.0% 253,064,866 /usr/local/lib/node_modules
d 3.1% 260,450,536 /usr/lib/jvm
d 4.4% 369,531,237 /usr/share/doc/texlive-doc
d 5.2% 429,055,696 /usr/local/lib/python3.5/dist-packages
d 5.2% 429,055,696 /usr/local/lib/python3.5
d 5.6% 461,789,323 /usr/lib/ghc
d 5.7% 473,685,763 /usr/share/doc
d 6.6% 549,563,745 /usr/bin
d 9.0% 743,990,153 /usr/local/lib
d 11.7% 972,273,271 /usr/local
d 16.9% 1,401,349,064 /usr/lib/x86_64-linux-gnu
d 27.7% 2,301,009,747 /usr/share
d 49.0% 4,070,197,838 /usr/lib
d 100.0% 8,309,946,131 /usr
Requires a standard installation of OCaml and Dune.
