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.

CHSH(1) User Commands CHSH(1)
NAME
chsh - change your login shell
SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username]
DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one.
chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries.
OPTIONS
-s, --shell shell
Specify your login shell.
-l, --list-shells
Print the list of shells listed in /etc/shells and exit.
-u, --help
Print a usage message and exit.
-v, --version
Print version information and exit.
VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in
the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you
are root.
EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.
SEE ALSO
login(1), passwd(5), shells(5)
AUTHOR
Salvatore Valente <svalente@mit.edu>
AVAILABILITY
The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
