How to print the list of packages installed on TeX Live to a file?

Question

OS: Ubuntu 11.10
TeX: Tex Live 2011
List of packages originally installed with Tex Live

Using the information given at the aforementioned question, I was able to see the list of packages in my current TeX Live installation. I wanted to save the list in a file. I tried using the "Edit>>Select All" option from the terminal. But using that I am able to save only a small sub-section of it. Is there a simple addition that I can make to the "list" command with "tlmgr" to make it print the output to a file?

Answer 1

Simply type the following command in a terminal / command prompt:

tlmgr list --only-installed > installed_texlive_packages.txt

which will save the list to a file called installed_texlive_packages.txt.

Answer 2

Compile it with -shell-escape option.

\documentclass[10pt]{article}
\usepackage[a6paper,hmargin=3mm,vmargin=12mm]{geometry}

\usepackage[T1]{fontenc}
\begingroup
\catcode`\^^M=12\relax%
\expandafter\gdef\expandafter\trimtok\detokenize{i}#1^^M{#1}%
\gdef\trimmer#1{\expandafter\trimtok #1}%
\endgroup

\newread\reader

\immediate\write18{tlmgr list --only-installed > installed-packages.txt}
\begin{document}
\tiny
\begin{enumerate}
\openin\reader=installed-packages.txt\relax
\loop
    \readline\reader to \data
    \unless\ifeof\reader
        \item \trimmer{\data}
\repeat
\closein\reader
\end{enumerate}
\end{document}

Answer 3

In 2020, type :

tlmgr info --only-installed

to get the list of installed package. Then do whatever you want with the output (like putting it in a file with > myfile.tx).

info command replaces former show and list commands (tlmgr manual: "The former actions "show" and "list" are merged into this action, but are still supported for backward compatibility".)
