Disable history for the current session

[zx8]

I realise that preceding a command with one or more space characters causes it to not be written to history, but I was wondering if there was a way to temporarily disable history for an entire session? From time to time, I need to repeatedly enter sensitive data (e.g customers' passwords) and it's cumbersome to constantly hit space before each command.

In bash, I'd simply just unset HISTFILE -- how would I do this in fish, if it's at all possible?

It's not possible easily (you can do some magic with fish_prompt by adding commandline " " to the prompt) - see #1156. I'm going to close as a duplicate of that for now.

Since this is the first issue I could find in google, functionality was implemented (if you follow the chain of linked issues):

According to the docs, it's the following:

set -x fish_histfile ""

Note that case matters. If this doesn't work (and you know you're on an older version of Fish) try FISH_HISTFILE as that's what it was when it was first implemented.

For the googlers: #102 (comment)

The above comment is no longer correct.

Use fish --private.
