environmental variable setting for sudo user

[bharani123]

The user is using "sudo -s" to become root.But when he become super user his environmental variable HISTFILE not getting set.And each time he is forced to run #export HISTFILE=/home/user1/.sh_history -- To access his command history. Can any one say how to set Environmental variable for this sudo user, so that it will be remain permanent.The entry in /home/user1/.profile haven't helped.

This seems like a security problem bound to happen if you want to share it.

But there are options in sudo to retain environment vars.

Dennis can i have the option which have to be used with sudo so that user will retain his own environmental variable setting.

the user is setting the environmental variable because "when he became superuser he is unable to access his command history".There the requirement is user should be able to access his own command history.
