I would like to know how much space is used my LaTeX install. I tried to do with apt but I am not sure it's possible. What I would like to do is to have a command like 

apt-cache list --show-install-size texlive*

outputing

128 MB

and of course the show-install-size doesn't exist.

Per binarysta's comment, dpkg-query works well for installed packages. If you are considering size before installing a package, you can use apt or apt-cache.

apt show. or apt-cache show gives an Installed-Size: field

stew ~ $ apt show texlive
Package: texlive

Description: TeX Live: A decent selection of the TeX Live packages
 The TeX Live software distribution offers a complete TeX system. It
 encompasses programs for typesetting, previewing and printing of TeX
 documents in many different languages, and a large collection of TeX macros
 and font libraries. . This metapackage provides a decent selection of the
 TeX Live packages which should suffice for the most common tasks. . The
 distribution also includes extensive general documentation about TeX, as
 well as the documentation accompanying the included software packages.

You could:

$ apt-cache show texlive | grep Installed-Size
Installed-Size: 72.7 kB

or for texlive*: 

$ apt-cache show texlive* | grep -E 'Package:|Installed-Size:'
Package: texlive-fonts-recommended
Installed-Size: 15029
Package: texlive-lang-portuguese
Installed-Size: 16440
Package: texlive-latex-recommended
Installed-Size: 31735
Package: texlive-base
Installed-Size: 74760
...

from man apt(8):

SYNOPSIS
       apt ... {list | search | show | ...}... 

...
       show (apt-cache(8))
           Show information about the given package(s) including its dependencies, installation and
           download size, sources the package is available from, the description of the packages
           content and much more. It can e.g. be helpful to look at this information before allowing
           apt(8) to remove a package or while searching for new packages to install.

  • Why the installed-size is 72.7 kB when it is actually close to 3 GB? – ado sar Oct 02 '22 at 10:26
  • texlive is not 3GB. – Stewart Oct 03 '22 at 08:44
  • I don't know the exact size, but for sure is not 72.7 kB which is reported by apt show. Therefore, Installed-Size doesn't provide any useful information. – ado sar Oct 03 '22 at 15:50
  • texlive itself is a tiny package which only contains copyright notices and bug scripts. Its real value is the dependencies it pulls in: texlive-latex-base (11.5MB), texlive-latex-recommended (31.3MB) and texlive-fonts-recommended (15.4MB). Those have even more dependencies such as texlive-latex-base depending on texlive-base (43.4MB) which depends on texlive-binaries (50.3MB) which depends on libc6 (13.1MB) which depends on libgcc-s1 (119kB). How deep you want to go is up to you. If you're interested in only packages that aren't installed, apt tells you on install. – Stewart Oct 04 '22 at 14:16

Please have a look at dpkg-query

dpkg-query -Wf '${Installed-Size}\t${Package}\n'

For rpm-based distros

rpm -qa --queryformat '%{SIZE} %{NAME} \n'

Output

Have you had a look at aptitude (apt-get install aptitude)? It is a user interface to packages, and it shows the download and install size. It is not a command line interface though....
