universe(1)                                           universe(1)



NAME
     att, ucb, universe - get and set universe

SYNOPSIS
     att [ command ]
     ucb [ command ]
     universe [ univ [ command ] ]

DESCRIPTION
     Each process contains a flag known as its current universe.
     The universe effects the translation of conditional symbolic
     links (see ln(1)), and therefore affects the process' view
     of the UNIX directory tree.  There are currently two sup-
     plied universes:  att and ucb, where att is the default
     universe.  The purpose of the universe concept is to achieve
     a higher degree of compatibility with both the AT&T System V
     Release 4 and 4.3BSD versions of UNIX.  The att universe
     creates a compilation environment that should appear to be
     AT&T System V Release 4, and the ucb universe creates a com-
     pilation environment that should appear to be 4.3BSD.

     The commands above, built directly into the shells, set and
     display the current universe and execute commands in the
     prescribed universe.  For example, to see what the current
     universe is, type universe.  To switch to the att universe,
     type att or universe att.  The universe command is more ver-
     satile in that it allows you to specify any string for the
     universe, rather than just att or ucb.

     The csh supports an additional functionality that allows a
     command to be executed in a specific universe without chang-
     ing the shell's universe. For example, to execute a command
     in the ucb universe without changing the shell's universe,
     type ucb command or universe ucb command.

     ln(1), intro(2), getuniverse(2), symlink(2)

BUGS
     sh and the ksh do not support the command argument on the
     att, ucb, or universe commands.
