How to uninstall Emacs?

How to uninstall Emacs?

[Rodolfo Medina]

Hi all.

I recently installed Emacs after downloading it from git repositories.  Suppose
I would like to uninstall it - I want to try how the Emacs distribution
provided by Debian works and then, perhaps, reinstall Emacs from git.  How can
I completely uninstall it?

Thanks for any help.

If you compiled and built it yourself with 'make install', go to the build
directory and try 'make uninstall'.

"make uninstall", of course.  Assuming you have the source tree for
the version you want to uninstall.

Or you could simply try the Debian one without uninstalling your
version.  When you compile from git sources and 'make install' it will
install emacs into /usr/local/bin/emacs.  Since PATH includes
/usr/local/bin ahead of /usr/bin calling emacs calls your locally
compiled binary first.

To avoid this you can simply call the system packaged version
directly.  You can do this even with your locally compiled one
installed in /usr/local/bin.

  /usr/bin/emacs

Calling it specifically by that path will invoke the system packaged
version.  You can verify this by looking at the emacs version.  The
version is usually displayed near the bottom of the start up splash
screen.  If not (I customize mine away) you can ask it directly.

  M-x emacs-version

If you have customizations in your dot emacs file you can test the
stock system configuration with the -q option.  The -q option
instructs emacs not to load an init file.

  /usr/bin/emacs -q

To be able to easily uninstall Emacs, I installed it in a prefix.
Configure it with
$ ./configure --prefix=/usr/local/$emacs_version
Then when you type
$ sudo make install
it will install into the chosen prefix.  Then create symlinks into
/usr/local/bin
$ sudo ln -sirv $prefix/bin/* /usr/local/bin

Later, to uninstall:
$ sudo rm -rI $prefix
$ find -L -type l /usr/local/bin
<Review the list of broken links in /usr/local/bin.  Confirm you want
to remove them all>
$ sudo find -L -type l /usr/local/bin -exec rm {} +

   Suppose I would like to uninstall it

method 42:

At some point, an asteroid will hit the earth.  That may or
may not wipe out civilization as we know it, but if you move
your computer to the right place, it will surely uninstall
Emacs.  At that point, it really doesn't matter what remains.

On an aptitude system (e.g. Debian, the Ubuntus, and
so on) you don't have to bother uninstalling programs
because they are just binaries (and sometimes scripts)
that lie passively unless you invoke them: they are
put into their respective boxes in the filesystem and
do not interfere with other programs - they are also
small, so disk space shortage cannot be remedied that
way either.

The package manager is the best way to not have to
deal with the make, configure, and 'make install'
dance, and you don't have to fiddle the symlinks,
either.

Of course it is still possible to uninstall - sudo
aptitude remove - but that is mostly done (seldom)
when the upgrade/installation process has had some
dust in its machinery and you need to give it
a fresh start.

Because of Jorge's smokescreens I got the impression
that I couldn't see the OP either, but now when I read
it this is the best answer. Mine is still correct in
principle tho :)

Thanks, I'll do so.

Thanks.  The two last lines relatives to `testing' will be used by the system
only if the first two, relatives to `sid', should fail?

I did so, and seems all right.

The end result is okay but it wastefully removes emacs24 and then
immediately installs it again.  'emacs24' is a dependency of the
current 'emacs'.  Why remove what will be immediately re-installed?

Maybe it was enough simply

 # aptitude install emacs

.  The reason to install `emacs' package having emacs24 already installed is
what you said above:

Yes, it's our present thread.
