Small python script to get packagesizes of installed packages

Hi,

having only allocated 10GB to my / partition, i needed to lose some big but unused packages. I wrote a small python script which accumulates sizes of installed packages.

It also finds packages missing files. But somehow reinstalling these package does not help.

Beware: This was an 30min hack-job. If this script eats your hard-drives and kidnapps your children, you are on your own.

License: GPL3
Usage: python PacmanPkgSize.py | sort -g

import subprocess
import re
import os

lineExp = re.compile('(.*)$')
sepExp = re.compile(' ')
o = subprocess.Popen('pacman -Ql', shell=True, stdout=subprocess.PIPE).stdout

pkgs = {}

for line in o:
        fields = sepExp.split(lineExp.match(line).group(1))
        try:
                pkgs[fields[0]] = pkgs.get(fields[0], 0) + os.lstat(fields[1]).st_size
        except OSError:
                print "Possibly broken package %s. Cannot lstat %s." % (fields[0], fields[1])

for pkg in pkgs:
        print pkgs[pkg], pkg

Output:

Possibly broken package ttf-cheapskate. Cannot lstat /usr/share/fonts/TTF/It.
Possibly broken package ttf-ms-fonts. Cannot lstat /tmp/ttf-ms-fonts/.
Possibly broken package ttf-ms-fonts. Cannot lstat /tmp/ttf-ms-fonts/andale32.exe.
Possibly broken package ttf-ms-fonts. Cannot lstat /tmp/ttf-ms-fonts/arial32.exe.

Re: Small python script to get packagesizes of installed packages

nice script only size of package output could be much easier if it was in mb's a simple calculation [divide by 1024?]

thanks

Re: Small python script to get packagesizes of installed packages

And maybe an option to sort from biggest to smallest or vice versa. Nice script though

Thanks for the nice replies.

@Mr Green: Display is in bytes because of 1. KISS, 2. If you wanted to postprocess the output, you would have to convert it back.
@moljac024: Unix philosophy. There is sort for sorting Just pipe through sort -g
