Both sets of commands define two variables that are available to everything running in the current shell execution environment.
The second set of commands (using export) also causes those two variables to be available to everything running in subshells and other execution environments initiated by the current shell execution environment after those variables are exported. Those variables will not be available to processes that were already running at the time those variables were exported no matter how those processes were initiated.

NAME
unalias - Removes alias definitions
SYNOPSIS
unalias alias-name...
unalias -a
Note
The C shell has a built-in version of the unalias command. If you are using the C shell, and want to guarantee that you are using the com-
mand described here, you must specify the full path /usr/bin/unalias. See the csh(1) reference page for a description of the built-in com-
mand.
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
unalias: XCU5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
Removes all alias definitions from the current shell execution environment.
OPERANDS
The name of an alias to be removed.
DESCRIPTION
The unalias utility removes the definition for each alias name specified. The aliases are removed from the current shell execution environ-
ment.
EXIT STATUS
The following exit values are returned: Successful completion. One of the alias-name operands specified did not represent a valid alias
definition, or an error occurred.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of unalias: Provides a default value for the internationalization variables that
are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization
variables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string
value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of
bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale used to
affect the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the
processing of LC_MESSAGES.
