Getting the source for something that doesn't seem to have an associated package?

I lately simply intended to consider the source code for sha1sum.

[email protected]:~/tmp-source-study$ apt-get source sha1sum
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to find a source package for sha1sum

The next point I did was to read the guidebook. The hand-operated stated coreutils. Yet I do not see anything like sha1sum.c, and also there is no affiliated Debian plan for sha1sum, regarding I can inform.

What should I be doing to get the source code for this tiny, standard program without needing to make use of an internet search engine, from the ease of my covering?

First, locate which plan the documents is from:

% dpkg -S /usr/bin/sha1sum
coreutils: /usr/bin/sha1sum

And after that install the source:

% apt-get source coreutils
