Unregister Viivi Environmental Variables (Unix csh-system)

1. Edit the Environment Configuration File

Remove the following two lines

	setenv VIIVI_HOME ${HOME}/Viivi/
	setenv PATH ${PATH}:${VIIVI_HOME}

appended at the end of the environment configuration file

	${HOME}/.cshrc

	${HOME}/.login

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 setenv as follows:

	% setenv VIIVI_HOME
	% setenv 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:

	% source ${HOME}/.cshrc

	% source ${HOME}/.login

where % is the prompt of csh.

[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

	% setenv PATH /bin:/usr/bin:${HOME}/bin:

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.

If there is no PATH descriptions in the environment configuration file, append the following line at the end of the environment configuration file.

	[Example]
	setenv PATH /bin:/usr/bin:${HOME}/bin:

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