# Determining which TeX Live collection a package belongs to

When using the TeX Live Manager or browsing CTAN, sometimes I want to know what TeX Live collection a particular package is found in. What is a convenient way to check?

-
With TeX Live collection you mean the TeX Live version or the used binary package name? The CTAN entry shows if the package is in the current (online) TeX Live version and what's the TeX Live package name is (usually identical to the real package name). –  Martin Scharrer Nov 14 '11 at 12:38
Also, do you mean the TeX Live collection from 'vanilla' TL or say when repackaged for a Linux distribution? –  Joseph Wright Nov 14 '11 at 13:25
I am referring to a TeX Live installation installed directly from tug.org/texlive. I don't see any collection information listed that Web site or CTAN. –  Village Nov 14 '11 at 13:50

The terminal command

``````tlmgr show abc
``````

``````package:     abc
category:    Package
shortdesc:   Support ABC music notation in LaTeX.
longdesc:    The abc package lets you include lines of music written in the ABC Plus language. The package will then employ the \write18 facility to convert your notation to PostScript (using the established utility abcm2ps) and hence to the format needed for inclusion in your document.
