Sorry, I should have thought a bit before I hit submit. ;^(

If the above echo statement does return a value for histfile, check the file's permissions.

Then you should export HISTFILE and HISTSIZE and restart your shell.

This is a very common problem for every HP-UX system. These two commands are missing from /etc/profile:

export HISTFILE=$HOME/.sh_history
export HISTSIZE=10000

Then for the root user, type:

umask 077
touch $HOME/.sh_history

This is required only for root - other users can use history immediately after they login. Now logout and log back in as root and type a simple command like pwd followed by: history. Since history is used a lot, I like to create an additional alias in .profile like this:

alias h='fc -l'

Now I just type h to get a history.
