Unix--GUI?
In general, does UNIX and its own "special versions" have a GUI interface? (Sort of what Linux has--example is it's generic terminal (shell) login screens, and then a 'startx' which loads the GUI interface.)
Does it depend on which "special version" in order for the manufacturer to include the GUI interface? For example, does Sun Solaris have a GUI interface in addition to its standard shell?
Also, you mentioned that "linux is 'the best of all unix-worlds'..." but you also mentioned that using linux, the user looses a lot of "commands/options/functions," which I have noticed when I use my version of linux. My question is, why is that? If its a "souped up" unix, why does it lack the power that unix has? Is it because linux is more catered towards home users, versus enterprise/corporate users (mainly the need for it to work on mainframes)?
Thanks.

MESG(1) Linux Programmer's Manual MESG(1)
NAME
mesg - display (do not display) messages from other users
SYNOPSIS
mesg [n|y]
DESCRIPTION
The mesg utility is invoked by a users to control write access others have to the terminal device associated with the standard error out-
put. If write access is allowed, then programs such as talk(1) and write(1) may display messages on the terminal.
Traditionally, write access is allowed by default. However, as users become more conscious of various security risks, there is a trend to
remove write access by default, at least for the primary login shell. To make sure your ttys are set the way you want them to be set, mesg
should be executed in your login scripts.
Options available:
n Disallows messages.
y Permits messages to be displayed.
If no arguments are given, mesg displays the present message status to the standard error output.
The mesg utility exits with one of the following values:
0 Messages are allowed.
1 Messages are not allowed.
>1 An error has occurred.
FILES
/dev/[pt]ty[pq]?
SEE ALSO
biff(1), talk(1), write(1), wall(1), login(1), xterm(1)
HISTORY
A mesg command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The mesg command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
Linux 1.2 10 March 1995 MESG(1)
