A customer who prefers tcsh complained that he had no history -- couldn't use the up/down arrow keys in the shell, and no .history file was being created. I tested this as a normal user with this in my .tcshrc :
set history = 50
logged out and in again, and he's right -- no history file, no arrow key history, no !! history.
History in other shells works fine for all users. Any idea what's breaking here or where to fix it? Thanks.
