Solved sh shell

[fernandel]

I have for root sh shell and user ksh.
I do not know what happened because in sh shell it keep history after upgrade to FreeBSD 14.2 .
It keep if I use su - or if I log in as root.
I didn't change anything.

Thank you.

Updating the operating system will not remove or overwrite user-level configuration/state files such as ~/.sh_history.

I do not know how. Before it didn't keep history across session.

Looks like persistent history was added as a feature in 2021.

Testing quickly, setting export HISTFILE="" in ~/.shrc appears to prevent persistent history retention.

The explanation likely involves the setting of the environment variable HISTFILE and how your particular Bourne or (various) Korn shells interpret that.

Also if the nominated $HISTFILE is not writable by the user, you will get unexpected behaviour.
