WSL doesn't "remember" last session commands

[ghost]

My build is 15063.158.

I ran different commands like ssh user@ip, I do some other actions, close the session and start another one later in that day but can't print commands from previous session with the arrows (top/button).

For some reason, WSL doesn't remember the commands from previous sessions.

I should note that I didn't felt such behavior in the last versions of Bash...

Did you happen to have multiple terminals open in parallel? In that case see https://unix.stackexchange.com/questions/1288/preserve-bash-history-in-multiple-terminal-windows

Did you happen to close bash in a non-graceful way, e.g. closing the window instead of writing exit? This could also be the issue.

In any event it is bash which is managing the history, not WSL. (aseering is right that WSL does have a say there.)

@CherryDT , "it is bash which is managing the history, not WSL" -- that's true, but WSL is managing bash :-) For example, WSL could attempt to close bash gracefully when the window is closed, so that it has a chance to save its history.

This all goes to #834 (and many friends). Every bash session except the last one cleans up correctly (saves history) when the window closes. The last one does not, because the last bash session dies by kernel panic. User voice is here.

@therealkenc Thank you.

Typing exit appears to work as a workaround (edit: also ctrl-d shortcut).

It appears from a cursory test that this was addressed as a happy side-effect of "Allow processes to run without an active terminal" (#709 et al) and possibly #2496. Going to mark as fixedinsiderbuilds 17046. If anyone is still seeing the lost history problem on insiders, ping the thread and I'll take a second look.
