GNU diffutils
1. Summary
This fast-track introduces GNU diffutils, version 2.8.1,
into the Solaris WOS.
Patch release binding is requested.
2. Discussion
Diffutils is a set of utilities for displaying
differences between text files.
These utilities are commonly used by open-souce
applications. A version is included with the CBE tools
for JDS, which is provided as a download on
opensolaris.org. They will also be used, if installed,
by Mercurial.
Diffutils is delivered as four command-line programs:
cmp, diff, diff3, and sdiff. Detailed information is
available from the Diffutils website [1] and a copy of
the manual is attached.
GNU diffutils is currently available in the Solaris
Companion CD (CCD). This proposal removes it from the
CCD and adds it to the SFW consolidation.
Non-GNU versions of these commands are already available
in Solaris. These are not, however, fully compatible
with the GNU variants, which are explicitly required by
some applications. The existing Solaris commands
have identical names and are installed in /usr/bin.
Therefore the GNU diffutils will be installed in
/usr/gnu, with g-prefixed symbolic links to each
command and manpage in /usr, as per the guidelines of
PSARC/2007/047, /usr/gnu [2].
