Hi bakunin,
Actually, the POSIX Standards have required conforming shells to support export commands with the SYNOPSIS forms:
Code:
export variable[=word]
      and
export -p

since 1992.

But, of course, if you're working on a project that is still using a pure Bourne shell, you'd still need to avoid assigning a value to a variable in an export command.

unset

asadmin-unset(1AS)						   User Commands						asadmin-unset(1AS)

NAME

       asadmin-unset, unset - removes one or more variables from the multimode environment

SYNOPSIS

       unset env_var [env_var]*

       Removes	one or more variables you set for the multimode environment. The variables and their associated values will no longer exist in the
       environment.

OPERANDS

       env_var		       environment variable to be removed.

       Example 1: Using unset to remove environment variables

       asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
       asadmin> export AS_ADMIN_PREFIX=server1.jms-service
       asadmin> export
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********
       AS_ADMIN_PREFIX=server1.jms-service
       asadmin> unset AS_ADMIN_PREFIX
       asadmin> export
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********

       Using the export command without the argument lists the environment variables that are set. Notice the AS_ADMIN_PREFIX is not in the  envi-
       ronment after running the unset command.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command

       asadmin-export(1AS), asadmin-multimode(1AS)
