export [ name [=value] ...]
export –p
export marks each variable name so that the current shell makes it automatically
available to the environment of all commands run from that shell. Exported
variables are thus available in the environment to all subsequent commands.
Several commands (for example, cd, date and vi) look at environment variables for
configuration or option information.
Variable assignments of the form name=value assign value to name as well as
marking name for export. The name can contain only the underscore and
alphanumeric characters from the portable character set.
Calling export without arguments lists, with appropriate quoting, the names and
values of all variables in the format Variable=″value″. If you reinput this format to
another shell, variables are assigned appropriately but not exported. The –p option
lists variables in a format suitable for reinput to the shell (see the description of the
–p option).
–p Lists variables in a form that is suitable for reinput to the shell:
export name="value"
export is a special built-in shell command.
export uses the following localization environment variables:
v LANG
v LC_ALL
v LC_MESSAGES
v NLSPATH
