Old utility I wrote for getting and sorting folders by size.

folder_size.py

#!/usr/bin/env python2

import os
from docopt import docopt
def get_size(start_path = '.'):
    """Gets the size of the path in bytes."""
    total_size = 0
    for dirpath, dirnames, filenames in os.walk(start_path):
        for f in filenames:
                fp = os.path.join(dirpath, f)
                if os.path.isfile(fp):
                    total_size += os.path.getsize(fp)
                
    return (start_path,total_size)

def list_sizes(start_dir,size_measurement="MB",verbose=False,exceptions=False):
    """Lists the size of the chosen directory."""
    if size_measurement == "B":
        offset = 1.0
    elif size_measurement == "KB":
        offset = 1024.0
    elif size_measurement == "MB":
        offset = 1048576.0

        offset = 1073741824.0
    else:
        print "Unknown size. Defaulting to MB."
        offset = 1024.0
    dirs = []
    if not os.path.isabs(start_dir):
        start_dir = os.path.join(os.getcwd(),start_dir)
    os.chdir(start_dir)

                print "Added dir",thing
        else:
            if verbose:
                print thing,"not a directory."
    sizes = []
    for x in dirs:
        try:
            sizes.append(get_size(x))
        except Exception,e:
            print "Failed to get",x
            if verbose or exceptions:
                print e
    sorted_sizes = sorted(sizes,key=lambda obj:obj[1],reverse=True)
    print "\n"
    for x in sorted_sizes:
        print x[0],":",str(float(x[1])/offset)+size_measurement
        
__doc__ =\
"""Improved folder size tools.

Used for getting and sorting sizes of folders to aid in freeing hard drive space.
It is recommended to pipe this utility into something such as less.

Usage:
  folder_size.py -h
  folder_size.py [-veu unit] <path>
  
Options:
  -h --help        Show this
  -u --unit unit   Specify unit. Valid units are: B, KB, MB, GB. Default is MB.
  -v --verbose     Display extra info
  -e --exceptions  Display exceptions
