Update update-alternatives of vim to new vim – statically compiled vim

2015-08-25Linuxkossboss

Update Alternative We will use Update Alternatives here, which is explained best by the first 2 man pages paragraphs (http://manpages.ubuntu.com/manpages/hardy/man8/update-alternatives.8.html):

"""
update-alternatives creates, removes, maintains and displays
information about the symbolic links comprising the Debian alternatives
system.

It is possible for several programs fulfilling the same or similar
functions to be installed on a single system at the same time. For
example, many systems have several text editors installed at once.
This gives choice to the users of a system, allowing each to use a
different editor, if desired, but makes it difficult for a program to
make a good choice for an editor to invoke if the user has not
specified a particular preference.
