pacsize: list of packages sorted by disk space usage

danielsoft · 2008-03-09 17:53:59

Hello,
I was wondering, which packages on my HDD are the largest, so I created this little script in Python
(another motivation was to learn Python more...)

it will just output a list of your packages, sorted by size, starting from the largest, to the standard output
the output is in format

272495 openoffice-base
138817 tetex
115541 acroread
102316 jre
95587 jdk
65836 kernel26
65649 wine
...

for example

here is the script:

#!/usr/bin/env python
import re
import os

class Package:
    def __init__(self,name,size):
        self.name = name
        self.size = int(round(float(size)))
    def __repr__(self):
        return `self.size`+" "+self.name    
    def __cmp__(self,other):
        return cmp(other.size,self.size) #desc

paclist = []        

re_name = re.compile(r'Name\s*:\s*(\S+)')
re_size = re.compile(r'Installed Size\s*:\s*([0-9.]+).*')

p = os.popen("pacman -Qi","r")

for line in p.readlines():
    match_name = re_name.match(line)
    match_size = re_size.match(line)
    if match_name : 
            package_name = match_name.groups(1)[0]
    if match_size :
            package_size = match_size.groups(1)[0]
            paclist.append(Package(package_name,package_size))

p.close()

paclist.sort()
for pac in paclist: print pac

I called it "pacsize".

There were a thread with several ways to achieve that result :

@danielsoft,

Thanks - that's very useful and it is a nice gentle introduction to Python for me!

sabooky · 2008-03-30 17:16:42

awk is awesome for small tasks like this.

pacman -Qi|awk '/^Installed Size/{print int($4), name} /^Name/{name=$3}'|sort -nr

That being said, great job of using python in an OO manner.
One comment on your python code.

return `self.size`+" "+self.name

back quotes are deprecated and will be removed in p3k. p3k changes use repr() instead of that's what you intended.

Here's an example of back quotes, repr(), and str()

>>> import datetime
>>> a=datetime.datetime.now()
>>> repr(a)
'datetime.datetime(2008, 3, 30, 13, 12, 29, 664490)'
>>> `a`
'datetime.datetime(2008, 3, 30, 13, 12, 29, 664490)'
>>> str(a)
'2008-03-30 13:12:29.664490'
>>> print `a`
datetime.datetime(2008, 3, 30, 13, 12, 29, 664490)
>>> print a
2008-03-30 13:12:29.664490

an even cleaner way would be to use string formatting

return "%d %s" % (self.size, self.name )

muczyjoe · 2008-12-14 18:45:00

sabooky: I made some modifications:

LC_ALL="C" /usr/bin/pacman -Qi | awk '/^Installed Size/{print int($4), name} /^Name/{name=$3}' | sort -nr

LC_ALL needs to be set, because, with other languages, this produces an empty output.
The absolute path also needs to be set, because users of pacman-color.
Btw. thanks for the script!

#!/usr/bin/env python2

import subprocess
from itertools import izip

p = subprocess.check_output(["pacman", "-Qi"])
p = p.split("Name")

def sizes():
    for i,x in enumerate(p):
        try:
            yield p[i].split("Installed Size : ")[1].split("\n")[0]
        except Exception:
            pass
def names():
    for i,x in enumerate(p):
        try:
            yield p[i].split(":")[1].split("\n")[0].strip()
        except Exception:
            pass

final_list = sorted(((size,name) for size, name in izip(sizes(), names())), key=lambda x: int(x[0].split(".")[0]))
for size, name in final_list:
    print "%s has a size of %s" % (name, size)

Another way to do it. Someone was asking for this on IRC so I hacked this together in 10 minutes. It abuses the try, except construct heavily, so please don't take this as being good python. This should be much faster than the original one though.

real 0m0.209s
user 0m0.147s
sys 0m0.030s

Also, the reason I'm bumping this thread is because the older ones might not work anymore, and someone else might benefit from this.

Edit: changed zip to izip, should improve speed for anyone who wants to use it

Allan updated his https://aur.archlinux.org/packages.php?ID=43779

falconindy · 2011-07-19 10:00:22

Not going to sell expac for me, karol?

expac '%m\t%n' | sort -h

Mine is better

This is what happens when I post before my first coffee.
I think Allan's script counts size differently.

Ahh yes, Allan's pulls in dependencies, which is a noble goal.

Okay expac is ridiculously faster. Everyone use that.

Came here looking for answers and was intrigued by sabooky's awk solution but it didn't take in to account the variable units (perhaps the output format has changed since 2008!). I spent a little time learning awk and came up with this:

cat > pacman_sizes.sh << EOF
#!/bin/sh
pacman -Qi | awk $@ '
    BEGIN {
        units["B"] = 0
        units["KiB"] = 1
        units["MiB"] = 2
        units["GiB"] = 3
        if (unit == "") unit = "MiB"
        if (min == "") min = 50
        if (pad == "") pad = 10
    }
    /^Name/ {name=$3}
    /^Installed Size/ {
        size = (int($4) * 1024^units[$5]) / 1024^units[unit]
        if (size > min) printf "% *.1f %s %s\n", pad, size, unit, name
    }
' | sort -n
EOF

chmod a+x pacman_sizes.sh
./pacman_sizes.sh -v unit=KiB -v min=100

The units aren't actually in the local database, they are just added by pacman, so you are having pacman add them, then you are taking them away again: cut out the middle man:

sed -n '/%NAME%/{n;h;}; /%SIZE%/ {n;H;x;s/\n/\t/;p;}' /var/lib/pacman/local/*/desc | sort -rnk2

But this is ancient anyways.
