combine the best of 'du' and 'tree'

Question

I'm wondering if we can combine the honesty of 'du' with the indented formatting of 'tree'. If I want a listing of the sizes of directories:

du -hx -d2

...displays two levels deep and all the size summaries are honest, but there's no indenting of subdirs. On the other hand:

tree --du -shaC -L 2

...indents and colorizes nicely however the reported sizes are a lie. To get the real sizes one must:

tree --du -shaC

...which is to say that you only get the true sizes if you let 'tree' show you the entire directory structure. I'd like to be able to always have correct size summaries regardless of how many levels of subdirs I want to actually display. I often do this:

tree -du -shaC | grep "\[01;34m"

... which prunes out everything but directories, and indents them nicely ... but there's no easy way to limit the display to just a given number levels (without the summaries lying). Is there a way? Perhaps I've missed the correct switches ...

Also checkout ncdu: http://dev.yorhel.nl/ncdu

Its page also lists other "similar projects":

gt5 - Quite similar to ncdu, but a different approach.

tdu - Another small ncurses-based disk usage visualization utility.

TreeSize - GTK, using a treeview.

Baobab - GTK, using pie-charts, a treeview and a treemap. Comes with GNOME.

GdMap - GTK, with a treemap display.

Filelight - KDE, using pie-charts.

QDirStat - KDE, with a treemap display.

QDiskUsage - Qt, using pie-charts.

xdiskusage - FLTK, with a treemap display.

fsv - 3D visualization.

Philesight - Web-based clone of Filelight.

You don't need to grep for the colour code, the -d option is list directories only.

This seems to do what you want:

$ tree --du -d -shaC | grep -Ev '(  *[^ ]* ){2}\['
.
├── [  18]  dir1
├── [  30]  dir2
├── [ 205]  junk
│   ├── [  18]  dir1
│   ├── [  30]  dir2
│   └── [  76]  dir3
├── [ 119]  merge
└── [  20]  stuff

 4.4K used in 10 directories

The grep command removes all lines that have (one or more spaces followed by a non-space followed by a space) twice, followed by a [.

If you want a depth of 1, change the bound count inside the {} curly braces to {1} rather than {2}. same if you want a depth of 3, change it to {3}.

You can turn this into a shell function, like so:

mytreedu() {
  local depth=''

  while getopts "L:" opt ; do
      case "$opt" in
          L) depth="$OPTARG" ;;
      esac
  done

  shift "$((OPTIND-1))"

  if [ -z "$depth" ] ; then
      tree --du -d -shaC "$@"
  else   
      local PATTERN='(  *[^ ]* ){'"$depth"'}\['
      tree --du -d -shaC "$@" | grep -Ev "$PATTERN"
  fi
}

This uses getopts to "steal" any -L option and its argument from the tree command line, if there is one. If there isn't a -L n option on the command line, then that works too.

All other options and args are passed to the tree command.

The local PATTERN=... line isn't really necessary. I only did it like that to make sure that it would fit on one line and not word-wrap here on U&L. The regular expression could and probably should just go directly on the tree | grep ... line.

Run it like this:

mytreedu 

or

mytreedu -L 2 /path/to/dir/

You can use dutree

• coloured output, according to the LS_COLORS environment variable.
• display the file system tree
• ability to aggregate small files
• ability to exclude files or directories
• ability to compare different directories
• fast, written in Rust

Answer 4

There isn't any perfect command tool to do this, But I found two ways that are closly.

• shows both folders and files' size, but not showing in a tree mode.

  du -ah --max-depth=1 /var/log

• shows in tree mode but only files' size, the folders are in counts

  tree -ah /var/log -L 1

Answer 5

Inspired by cas, I'm now doing this:

treee ()
{
    integer levels=$(( ($1 + 1) * 4 ))
    tree --du -shaC | grep "\[01;34m" | grep -Ev "^[^\[]{$levels}\[*"
    du -sh .
}
