after install freebsd 7.0, I think I immediately install port tcshrc which give alot of tcsh function to my personal id but not root.
afterthat I found out my id do not record history after I log off.
I found unset histfile in .tcshrc.set, but remove it won't solve it, neither if
you do set histfile=.history
history function in my root id seems to be functioning normally.

I solved the issue by rename all .tcshrc, login to id and logoff again.

that's all! guys.
