duem: du emulator. (pronounced Do 'em) Emulates the Unix du command (disk usage), which is commonly used to go down directory (folder) trees and report back on disk usage below each directory.
- Runs from command line, simple (<300 lines) Python 3.8 script
- No additional Python Std Lib modules required, it only imports: sys, os, optparse, glob
- Links are not followed, and their disk space used is ignored
- Pre-compiled executable for Windows users who don't have Python installed (see below)
Basically does something similar to du, but in addition:
- has an option, -d or --depth, to only report back for a specifed depth down the tree. Actual disk usage below a point is calculated all the way down the tree; --depth only limits what is actually displayed. Also, if depth requested was larger than the actual depth of the tree, informs that only X levels were necessary.
- In addition to reporting how much disk usage in and below a directory, reports how many regular files are within the directory, and how much total disk space they use. (If there are no other sub-directories below, then only the number of regular files is reported, not their disk usage.)
- The unit for disk space reporting is chosen automatically to be human-readable, depending on the size, however command line options -b, -k, -m, -g can be used to override and report in bytes, kilobytes, etc...
duem operating on a directory called Lookup containing:
AMR/ CPP/ Cprism/ Dyssa/ Figs/ Hydrogen11/ Laminar/ Manual/ Methane22/
Methane32/ Parallel/ Preuse/ Simsim/ Turbjet/ Zerod/
will give, with duem -d 10 Lookup:
256.2M Lookup [no regular files]
|->10.6M Lookup/Dyssa [25 files: 3.6M]
|->7.0M Lookup/Dyssa/Figs [85 files: 7.0M]
|->14.5K Lookup/Dyssa/Figs/.xvpics [5 files]
|->1.2M Lookup/Hydrogen11 [4 files]
|->2.5M Lookup/Methane32 [32 files: 2.2M]
|->347.2K Lookup/Methane32/src [42 files]
|->3.6K Lookup/Methane32/.xvpics [1 files]
|->26.6M Lookup/Laminar [19 files]
|->20.3K Lookup/Zerod [23 files]

|->348.7K Lookup/CPP [35 files: 323.8K]
|->20.9K Lookup/CPP/Monte [5 files]
|->1.7M Lookup/Preuse [10 files]
Was only necessary to go down 3 levels. --depth 10 was requested.
The file duem_1.5.2.exe is the actual duem binary (made with pyinstaller) and can be placed in any folder the user desires. It has been tested on Windows 10.
Either add this folder to your PATH environment variable, or choose a folder already in your PATH. Or you could add a file named duem.bat which will consist of something like the following lines:
@echo off
REM This is to run duem, the du emulator
C:\Users\YOURUSERNAME\PLACE_YOU_DOWNLOADED_TO\duem\duem.exe %*
REM python C:\Users\YOURUSERNAME\workspace\Du\duem.py %*
i.e. it points to the location to which you placed the .exe file. Hopefully then, typing duem at a DOS prompt will work: Open a DOS window using cmd, test by typing duem --version or duem --help.
Old code version 1.4.1 zip file still available, is in Python 2.7. Works the same as this.
Decent documentation at www.twentypede.com/leg4 and the sha256 sums are viewable there too.
