There is no simple way to do this. Apart from
those user-written ado files that remain private,
those in the public domain and on the internet may be
in many different places:

1. The Stata Journal/Stata Technical Bulletin website.

2. SSC.

3. All other institutional and personal websites.

There is no central directory, and long may that remain
so. Rather, -findit- will find (most) of what is there
is, so long as you feed it keywords.

Even if it were possible, it would not be a good idea:

1. You would still have the problem of identifying
what you had installed and working out what was any
good to you.

2. You would be installing software of different degrees
of generality and quality. Some of it has also been
superseded by other programs. Some of it is buggy.

3. There is no guarantee that different user-written programs will
use distinct filenames.



I would add that a common problem discussed on this list is that a user will do, say, 'findit instrumental variables' and learn that a routine named ivreg2 is available. The first mention of that in - findit's- output will be in the Stata Journal website. But that version is not the most recent version; the most recent version is available from SSC. -adoupdate-, although smart, is not smart enough to figure this out (and doing so, given the structure of Stata packages, is close to logically impossible). If you install the most recent version from SSC, though, -adoupdate- will help you make sure it is up to date.

So mindlessly installing stuff from _both_ Stata Journal / Stata Tech Bulletin and SSC is generally dangerous without noting which is the newer routine. Many routines which have appeared in SJ/STB have updated versions on SSC.
