history of commands

I would like to log all the commands I type (on the terminal) to a file. The command "history" does this only for current terminal only. I typically keep around 10 terminals open.

Thanks,
j

Note: I do not have root access.

I am using tcshell.

create a .logout file at your home
write a command to append your history to a specific file

examples
history >> my_history

if u know exactly the history filename
cat history_filename my_history
