Can anyone enlighten me about the difference between /usr/has/bin/vi and /usr/xpg4/bin/vi? ":version" yields "Version SVR4.0, Solaris 2.5.0" in both cases, ldd the same libs, too, but the binaries differ sightly in size: 218 vs 223 KB.

(I wasn't able to discern a man page for the xpg4 vi in oder to compare it against /usr/has/man/man1has/vi.1has)

has is original /usr/bin versions, replaced with modern versions with incompatible changes.

so original vi moved to has and vim is installed instead, for example.

i understand the vi/vim difference. But what is the vi/vi (has/xpg4) difference?

man is only stating that in case of xpg4 and xpg6, when -t and -c are both present, -t is processed first.

I guess, to get exact diffs, you must read the source and search for XPG related differences;)

added to the TODO list :-) thx for the info!
