Enabling command history on HP-UX

After installing HP-Unix you will notice that the command history is not working. That is pressing Esc+k returns nothings. If you execute the history command you will see error message like this:

sh: fc: Cannot access or open the history file.

You have to manually enable this feature. To do this add the following two line on your ~/.profile file and create the .sh_history file using touch command. Then log in again. You will see it is working.

HISTFILE=/.sh_history
export HISTFILE
