Getting directory size using ruby

Detlef_R · January 22, 2014, 2:24pm

Hi, I want to measure directory size using Ruby. I can use
sys/filesystem gem but I didn’t understand from examples how can it
ensure this?

github.com

djberg96/sys-filesystem/blob/main/examples/example_stat.rb

######################################################################
# example_stat.rb
#
# Example program that demonstrates the FileSystem.stat method.
# Use the 'rake example' task to run this program.
######################################################################
require 'sys/filesystem'
include Sys

p Filesystem::VERSION

stat = Filesystem.stat("/")
puts "Path: " + stat.path
puts "Block size: " + stat.block_size.to_s
puts "Fragment size: " + stat.fragment_size.to_s
puts "Blocks free: " + stat.blocks_free.to_s
puts "Blocks available: " + stat.blocks_available.to_s
puts "Bytes free: " + stat.bytes_free.to_s
puts "Bytes available: " + stat.bytes_available.to_s
puts "Files/Inodes: " + stat.files.to_s

This file has been truncated. show original

I musn’t do du -sh directory and using recursive File.size(“…”){ …}
will be very slow for me, so how can I get directory & file
size, can you suggest me something for this?

Thanks.

Traverse with Find or Pathname and sum individual sizes.
