how much space does a given package, and dependencies, cost?
Simplest and bug free way to get the space used by a program and all its dependencies is to use apt itself. Note dependencies that are not used by another program, but installed with a package, is not considered as they are not removed.
Simply
sudo apt-get --assume-no autoremove PACKAGENAME
or
apt-space-used-by() { sudo apt-get --assume-no autoremove $@ | grep freed | cut -d' ' -f4-5 ;}
usage apt-space-used-by PACKAGENAME
This python script looks promising (bigpkg - find packages that require a lot of space on your system)
Simply try following command ( to get disk space freed by purge):
echo -n | sudo apt-get purge <package> | grep "disk space will be freed"
or
echo -n | sudo apt-get purge --auto-remove <package> | grep "disk space will be freed"
where replace
<package>
with yourpackage-name
( example:gimp
)This will not purge package with dependencies but only gives how much disk space will be freed with help of
grep
!
Using
dpkg --print-avail
orapt-cache show
:apt-cache show <package> | grep "Installed-Size"
or
dpkg --print-avail <package> | grep "Installed-Size"
This will display installed size of
<package>
.Example:
$ apt-cache show gimp | grep "Installed-Size" Installed-Size: 15024
Sort list of installed packages by size
dpkg-query -W -f='${Installed-Size;8} ${Package}\n' | sort -n
You can use more for page-wise:
dpkg-query -W -f='${Installed-Size;8} ${Package}\n' | sort -n | more
Above list packages according to size acceding, you can use
tail
to list packages consuming top size as follows:dpkg-query -W -f='${Installed-Size;8} ${Package}\n' | sort -n | tail
Using
dpigs
(from mandpigs
):dpigs - Show which installed packages occupy the most space
dpigs sorts the installed packages by size and outputs the largest ones. Per default dpigs displays the largest 10 packages. You can change this value by using the -n option (see "OPTIONS"). The information is taken from the dpkg status file with grep-status(1)
This Can be installed by:
sudo apt-get install debian-goodies
Example of run command$ dpigs 115449 wine1.6-i386 110356 linux-image-extra-3.13.0-24-generic 103828 libreoffice-core 86240 fonts-horai-umefont 74016 libreoffice-common 72709 liboxideqtcore0 61736 linux-headers-3.13.0-24 60821 libpyzy-1.0-0 59477 firefox 59443 thunderbird
Finding size of Unused package:-
popularity-contest (8) - list the most popular Debian packages popcon-largest-unused (8) - List size of unused packages
First run
popularity-contest
and thenpopcon-largest-unused
, This will help you to find size of unused package. Visit man-pages for more information.
I tried my best to provide useful commands by steps.
Hope these helps!
apt-cache show packagename
lists, among other things, the installed size of a package and the dependencies of a package. There's also apt-cache rdepends packagename
to list the packages that use that package.
You might want to use the latter command and apt-cache policy packagename
to determine if a reverse-depdendency is installed.
