du (Disk Usage) with golang

It's a simple du alike app that prints the size of the folder (and its sub-folders)

Installation

go get -u github.com/missedone/dugo

Usage

Usage: dugo [options...] <target_dir>

Options:
  -h  "Human-readable" output.  Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte.
  -t  threshold of the size, any folders' size larger than the threshold will be print. for example, '1G', '10M', '100K', '1024'
  -d  list its subdirectories and their sizes to any desired level of depth (i.e., to any level of subdirectories) in a directory tree.

Example

  1. list with max depth as 1 (equivalent to du -h -d 1 /opt/vagrant
dugo -h -d=1 /opt/vagrant
2.3M	 /opt/vagrant/bin/
212.1M	 /opt/vagrant/embedded/
214.4M	 /opt/vagrant/
  1. list and only show the folders larger than threshold
dugo -h -d=1 -t=100M /opt/vagrant
212.1M	 /opt/vagrant/embedded/
214.4M	 /opt/vagrant/

so in this example, /opt/vagrant/bin/ was not shown on the output since its size is under the threshold '100M'.
