Unregister Viivi Environmental Variables (Unix sh-system)

1. Edit the Environment Configuration File

Remove the following four lines

	VIIVI_HOME=${HOME}/Viivi/
	export VIIVI_HOME
	PATH=${PATH}:${VIIVI_HOME}
	export PATH

appended at the end of the environment configuration file

	${HOME}/.profile			for sh
	${HOME}/.kshrc				for ksh
	${HOME}/.bashrc				for bash

and then save the environment configuration file.

2. Unregister Viivi Environmental Variables

Remove the strings which were registered to the Environmental variables VIIVI_HOME and PATH, using the shell command set as follows:

	$ set VIIVI_HOME=
	$ export VIIVI_HOME
	$ set PATH=
	$ export PATH

3. Read the Environment Configuration File

In order for the new settings to take effect, read the environment configuration file edited above as follows:

	$ . ${HOME}/.profile			for sh
	$ . ${HOME}/.kshrc			for ksh
	$ . ${HOME}/.bashrc			for bash

where $ is the prompt of sh / ksh / bash.

[Note]
After performing the above operations, if you find errors that commands are not found, the cause is that there are no descriptions for PATH in the environment configuration file.

For now, please input as follow

	$ PATH=/bin:/usr/bin:${HOME}/bin:
	$ export PATH

to enable the usual commands.

After confirming that you can use the usual commands, please write down the above setting for PATH in the environment configuration file.

[Example]
If there is no PATH descriptions in the environment configuration file, append the following two lines at the end of the environment configuration file.

	PATH=/bin:/usr/bin:${HOME}/bin:
	export PATH

And then, repeat the operation 3. to read the environment configuration file.
