[SOLVED] Looking for command to list certain installed apps by size.

linustalman · 01-16-2019, 06:54 AM

Hi.

What command would list a few apps (e.g. geany, leafpad, pluma) and output their size in ascending order?

I saw a recent example from someone using an Arch system:

Code:

pacman -Qi lxterminal xterm | grep -i size

I'm using Debian.

Thanks.

The thing is, there is a difference between the size of a package and the size of the disk space that a package and its configuration files take up on your disk once the package is installed and run. Finding the former is easy but the latter is more difficult as it would involve having to add together the sizes of all the files and configuration files connected to the package wherever they are on the disk, bearing in mind that some of these files may be jointly shared with other packages/applications. And that's before we take dependencies into account.

So which of these are you looking for? (please say the former...

).

... and please tell us if you want absolute files size (ls) or resident files size on your filesystem (du)

Hi hydrurga. Let's go with the former for now.

Hi l0f4r0. Both if you can.

Code:

apt-cache show leafpad geany pluma| grep -i '^package\|size'

i think i prefer:

Code:

for i in leafpad geany pluma; do apt-cache show "$i" | grep -i '^package\|size'; printf "\n"; done

how to sort that is beyond me.

Code:

for i in geany leafpad pluma; do apt-cache show "$i" | grep -i '^installed-size:'; done | sort -V
for i in geany leafpad pluma; do apt-cache show "$i" | grep -i '^size:'; done | sort -V

run separate do sort, but lack the name of the package.

I have NO idea if the installed packages database keeps those sizes in Debian, it is pure package manager dependant.

I.e. in Slackware it is

Code:

grep "PACKAGE SIZE:" /var/log/packages/{list of packages}|sort -k 4 -n
or, in -current (the PATH has been changed in recent versions):
grep "PACKAGE SIZE:" /var/lib/pkgtools/packages/{list of packages}|sort -k 4 -n
and to get just the uncompressed size
grep "UNCOMPRESSED PACKAGE SIZE:" <rest of the command line>

which works because in Slackware the installed package list contain just plain text files.

Beaten to it by nodir.

Just to add that this can also be done by using dpkg-query but this only works for packages installed on your system whose details are contained within the dpkg database.

Code:

for i in leafpad geany pluma; do dpkg-query -Wf '${Installed-Size}\t${Package}\n' "$i" | sort -n; done

Note also that calling apt show rather than apt-cache show gives a slightly different figure and adds a kB on the end.

I like the first one. Thank you nodir.

Perfect! Thanks again hydrurga.
