Mistake happen.

Yesterday I was tired and working on a friend serveur. The ssh prompt was different and I entered the password from a account while the remote port has hang up on me. So effectively typing “password” straight on my shell.

His password is in my history now. I removed it but that type of thing happen all the time. ( Not that much in a professional settings, password tends to fade away )

Pro-tip: if you wanna hide stuff from your shell history, enter a space/blank before the actual command.

Not that it probably would have helped in this situation, but maybe useful for others.

Usually if I have to enter secrets in my shell, I do something like this in order to save the useful stuff to history but hiding the secrets:

- ` export PASSWORD=hunter2` (notice the space before "export")

- `service-cli login username $PASSWORD` (no space before, gets saved to shell history)

While ignoring commands preceded by a space character is absolutely one of my very favorite shell features, it usually isn't enabled by default (YMMV).

HISTCONTROL=ignorespace # bash

setopt hist_ignore_space # zsh

These go into ~/.bashrc or ~/.zshrc, respectively. zsh is really smart about this and always enables you to retrieve the immediate previous line with arrow-up, no matter whether it's got preceding whitespace or not.

+1 to prefixing with a space. hiSHtory supports this out of the box so that anything prefixed with a space isn't recorded (even if your shell doesn't do that by default!). And if you do ever mess up, `hishtory redact` can be used to delete history entries.

Other options:

- read -s PASSWORD

- service-cli login username $(cat)

At least you probably don't want to use `export` when setting the variable.

why use `export` ? That is a terrible idea.
