Enable History Logging In TCSH Shell

Question

How can I enable logging of all the commands entered in the tcsh shell?

I've tried:

1. Setting the $history variable to 100.
2. The $savehist to 99.
3. Set the $histfile to $home/.history

Typing commands into the shell doesn't save the commands in the history file.

Answer 1

In my .tcshrc:

set history=2000
set savehist=(2000 merge)
